Program 3.5 - Conversion Program   - NOW using cin statements to gather input from user

Concepts Covered:  Chapter 2 – cout ,   math, data types, Chapter 3 , gathering both numeric & string input from user

Programs 2-21, 2-22, 2-23, 2-28 should help with math and programs 3.5, 3.17 and 3.19 should help you with the new concepts introduced with this program.

Program Purpose:  To help you understand the concept of using both proper numeric variables and string variables. To give you practice using the C++ math operators. To give you practice getting both numeric input and string input from a user. To give you practice overriding the default behavior of C++ for numeric formatting. Lastly, to appreciate the flexibility of the cout object by passing it string variables, string literals, and numeric variables.

Background:  Your instructor is an avid (some would say obsessed) bicyclist.  Rides of 40 to 50 miles are not uncommon. Your instructor also uses an indoor training program called Zwift. It uses the metric system which is kilometers biked (instead of miles), and meters climbed (instead of feet).     You need to help out your metrically challenged professor and write a conversion program that converts kilometers to miles and meters to feet.

For example, if I told some of my non-biking friends that I rode 40 kilometers, many of them would be impressed.  Well, in miles that is only 24.8 miles.   Conversely, if I told them I climbed 1000 meters they may not be impressed.  But, 1000 meters is 3,280 feet which is not too shabby here in the Midwest.

Oh, did I mention, this also applies to runners, especially in terms of kilometers.

So your job commission is to write a C++ program which will convert kilometers to miles and meters to feet.

PROGRAM SPECIFICATIONS:

Insert program heading with your name, course, section, program name, AS WELL AS brief documentation of program purpose at the top of your program.

Create your c++ code.

INPUT SECTION

Create 4 numeric variables to hold the following:  meters, feet, kilometers, and miles.

Create 2 string variables: one to hold the activity type:  biking or running and the other to hold a person’s name.

Prompt the user for their name. You should get the user's full name! Example   Jimmy C   or John Bonham

Prompt the user (using their name) for which activity they did. - biking or running

Prompt the user for how many kilometers

Prompt the user for how many meters they climbed

PROCESSING SECTION

Perform the necessary math operations to convert kilometers to miles and meters to feet.

Kilometers to miles formula:

1 kilometer is equal to 0.621371 miles (often shortened to .62). 1 mile is equal to 1.609344 kilometers. Thus, to convert kilometers to miles, simply multiply the number of kilometers by 0.62137.

Meters to feet formula:

Multiply any meter measurement by 3.28 to convert to feet. Since one meter = 3.28 feet, you can convert any meter measurement into feet by multiplying it by 3.28.

1 meter x 3.28 = 3.28 feet

5 meters x 3.28 = 16.4 feet

2.7 meters x 3.28 = 8.856 feet

OUTPUT SECTION

Using cout statements, display the output listing name, activity, kilometers, miles, meters and feet. For formatting of numeric variables, use 2 digits of precision to right of decimal point.with values shown above.

There are two calsses: node.py and a5.py. The a5.py contains three important methods:

• Length -> Outputs the length of the linked list
• Insert -> Inserts an element into the linked list
• PrintStructure -> Prints the entire linked list starting from the head

The task is to fill in these methods given in the a5.py. Hints are given to you inside the a5.py class so make sure to check them out. Note that one of the important concepts in this example is that when a new element is inserted into the list, it gets inserted into it’s appropriate (sorted) position. Please take a look at the examples to see how random values are inputted and the result is sorted.

Imagine that you are a user in a hurry that types 2O (oh) rather than 20 (zero) as the height. What happens to your program? If the user enters a value that could not be converted to numeric type, allow 3 additional opportunities to enter a new value. If the user fails to enter a correct value after 4 attempts, inform them of such failure and allow the program to end without crashing.

Question: Can someone help me with this?

My original code:

# I put the area calculations of both the triangle and trapezoid up, so that the code could run through them both properly.
def triangle(height, base):
area_triangle = height * base * 0.5
print "the area of your triangle equals %s" % (area_triangle)
def trapezoid(height, base1, base2):
area_trapezoid = ((base1 + base2) / 2) * height
print "the area of your trapezoid equals %s" % (area_trapezoid)
# Giving the option to choose triangle or trapezoid area.
shapes = ["triangle", "trapezoid"]
# I gave my code a title and put my name on it.
print "Area calculator"
print "Made by Alison Voigt"
print "-------------------------------"
# Asking the user to enter either the triangle or the trapezoid to move on to the area calculation.
def calculation():
print "please type the name of your shape"
print "(triangle, trapezoid)"
# Once the user chooses a shape they are asked to enter in the height, and base(s) for the shape of their choosing.
user_shape = raw_input()
if user_shape == shapes[1]:
trapezoid(height = float(raw_input("please type the height of the trapezoid.")), base1 = float(raw_input("please type the base1 length of the trapezoid.")), base2 = float(raw_input("please type the base2 length of the trapezoid.")))
elif user_shape == shapes[0]:
triangle(height = float(raw_input("please type the height of the triangle.")), base = float(raw_input("please type the base length of the triangle.")))
# If the user enters in wrong answer the code will tell you to try again.
else:
print "That's not in the choices!, Try again."
calculation()
# The user is now given the option to calculate the same shape or the other.

1. If I can assume "not P" and derive "not Q", I have completed an indirect proof of the statement "P → Q".

T/F? Why?

2. If I want to prove "P → (x XOR NOT y)", it suffices to prove "P → (x AND y)".

T/F? Why?

3. Suppose I assume "A" and derive "B". Then I start over, assume "not B", and derive a contradiction. Then I may conclude that A is a tautology.

T/F? Why?

4. Suppose I first assume "A xor B" and prove "C".

Then I start over, assume "P", and prove "A and not B".

Finally I start again, assume "Q", and prove "not A and B".

Then I may conclude "(P or Q) → C".

T/F? Why?

5. Suppose I first assume A and derive B.

Then I start over, assume "not C", and derive "not B".

Then I start over, assume "C and not A", and derive "0".

I can now conclude that A, B, and C are all equivalent to one another.

T/F? Why?

b) Discuss and develop a theoretical network architecture for a small business in the area that wishes to expand into new facilities, like a colocation center in the downtown area.

Q. In java, I would like to know, especially how the program detect there is an error which is user should put only numerical data but if user put letter data (five, sixty instead of 5,60), *I want the program display "Invalid data. Please try again" instead of long error message(from the IDE)* when user put letter data(five, sixty stuff...) and GO BACK TO THE BEGINNING SO USER CAN PUT THE DATA AGAIN!

Write a program that counts change. The program should ask for the number of quarters, the number of dimes, the number of nickels and the number of pennies. The program should then compute the value of all the coins and tell the user how much money there is, expressed in dollars. Display a title at the top of the screen when the program first runs. You must use constants for the value of each coin type. Multiply the number of each coin times the value for each coin (the defined constant). Refer to the PowerPoint or video on the use of the constants.

1) if quarters =100 dimes = 100 nickels = 100 pennies = 99

=>expected result = 40.99

2) if quarters = hundred dimes = hundred nickels = nine pennies = hundred

=> expected result ""Invalid data. Please try again" (GO BACK TO THE BEGINNING, SO USER CAN PUT THE DATA AGAIN!) <- this is the part i am struggling. Please Help!

Problem 1:

More than 2500 years ago, mathematicians got interested in numbers.

Armstrong Numbers: The number 153 has the odd property that 13+53 + 33 = 1 + 125 + 27 = 153. Namely, 153 is equal to the sum of the cubes of its own digits.

Perfect Numbers: A number is said to be perfect if it is the sum of its own divisors (excluding itself). For example, 6 is perfect since 1, 2, and 3 divide evenly into 6 and 1+ 2 + 3 = 6.

Input File

The input is taken from a file named number.in and which a sequence of numbers, one per line, terminated by a line containing the number 0.

Output File

All the numbers read from the input file, are printed one per line followed by a sentence indicating whether the number is or is not Armstrong number and whether it is or is not a perfect number. Sample Input 153 6 0 Sample Output 153 is an Armstrong number but it is not a perfect number. 6 is not an Armstrong number but it is a perfect number.

Note: the program must be write in java

Create a dynamic array-based Queue ADT class in C++ that contains enqueue(Inserts newElement at the back ) and dequeue(Removes the frontmost element ). If the size of the array is equal to the capacity a new array of twice the capacity must be made.

The interface is shown:

class Queue {
    private:
        int* elements;  
        unsigned elementCount;  // number of elements in the queue
        unsigned capacity;      // number of cells in the array
        unsigned frontindex;    // index the topmost element
        unsigned backindex;     // index where the next element will be placed

    public:
        // Description: Constructor
        Queue();


        // Description: Inserts newElement at the back (O(1))
        void enqueue(int newElement);

 
        // Description: Removes the frontmost element (O(1))
        // Precondition: Queue not empty
        void dequeue();


        // Description: Returns a copy of the frontmost element (O(1))

Powerball. In this assignment you are to code a program that selects 20 random non-repeating positive numbers (the Powerball Lottery numbers), inputs three numbers from the user and checks the input with the twenty lottery numbers. The lottery numbers range from 1 to 100. The user wins if at least one input number matches the lottery numbers.

As you program your project, demonstrate to the lab instructor displaying an array passed to a function. Create a project titled Lab6_Powerball. Declare an array wins of 20 integer elements.

Define the following functions:

• Define function assign() that takes array wins[] as a parameter and assigns 0 to each element of the array.

  Hint: Array elements are assigned 0, which is outside of lottery numbers' range, to distinguish elements that have not been given lottery numbers yet.

  Passing an array as a parameter and its initialization is done similar to the code in this program.

  • #include <iostream>
    using std::cout; using std::endl; using std::cin;
    
    // initializes the array by user input
    void fillUp(int [], int);
    
    int main( ) {
       const int arraySize=5;
       int a[arraySize];
    
       fillUp(a, arraySize);
    
       cout << "Echoing array:\n";
       for (int i = 0; i < arraySize; ++i)
          cout << a[i] << endl;
    }
    
    // fills upt the array "a" of "size"
    void fillUp(int b[], int size) {
    
       cout << "Enter " << size << " numbers: ";
       for (int i = 0; i < size; ++i)
          cin >> b[i];
    }

• Define a predicate function check() that takes a number and the array wins[] as parameters and returns true if the number matches one of the elements in the array, or false if none of the elements do. That is, in the function, you should write the code that iterates over the array looking for the number passed as the parameter. You may assume that the number that check() is looking for is always positive.

  Hint: Looking for the match is similar to looking for the minimum number in this program.

  • #include <iostream>
    using std::cout; using std::endl; using std::cin;
    
    int main(){
    
       const int arraySize=5;
       int numbers[arraySize];  // array of numbers
    
       // entering the numbers
       cout << "Enter the numbers: ";
       for(int i=0; i < arraySize; ++i)
            cin >> numbers[i];
    
      // finding the minimum
      int minimum=numbers[0]; // assume minimum to be the first element
      for (int i=1; i < arraySize; ++i) // start evaluating from second
            if (minimum > numbers[i]) 
               minimum=numbers[i];
      
      cout << "The smallest number is: " << minimum << endl;
    
    }
    

• Define a function draw() that takes array wins as a parameter and fills it with 20 random integers whose values are from 1 to 100. The numbers should not repeat.

  Hint: Use srand(), rand() and time() functions that we studied earlier to generate appropriate random numbers from 1 to 100 and fill the array. Before the selected number is entered into the array wins, call function check() to make sure that the new number is not already in the array. If it is already there, select another number.

  The pseudocode for your draw() function may be as follows:

      declare a variable "number of selected lottery numbers so far",
                   initialize this variable to zero
      while (the_number_of_selected_elements is less than the array size)
           select a new random number
           call check() to see if this new random number is already in the array
           if the new random number is not in the array
               increment the number of selected elements
               add the newly selected element to the array
  
     

• Define function entry() that asks the user to enter a single number from 1 to 100 and returns this value.
• Define function printOut() that outputs the selected numbers and user input.
  Hint: Outputting the array can be done similar to echoing it in this program.

  • #include <iostream>
    using std::cout; using std::endl; using std::cin;
    
    // initializes the array by user input
    void fillUp(int [], int);
    
    int main( ) {
       const int arraySize=5;
       int a[arraySize];
    
       fillUp(a, arraySize);
    
       cout << "Echoing array:\n";
       for (int i = 0; i < arraySize; ++i)
          cout << a[i] << endl;
    }
    
    // fills upt the array "a" of "size"
    void fillUp(int b[], int size) {
    
       cout << "Enter " << size << " numbers: ";
       for (int i = 0; i < size; ++i)
          cin >> b[i];
    }
    

The pseudocode your function main() should be as follows:

  main(){
      declare array and other variables
  
      assign(...) // fill array with 0
      draw(...)       // select 20 non-repeating random numbers
      iterate three times
            entry(...)      // get user input
            use check () to compare user input against lottery numbers
            if won state and quit
      printOut(...)   // outputs selected lottery numbers
  }
  

Note: A program that processes each element of the array separately (i.e. accesses all 20 elements of the array for assignment or comparison outside a loop) is inefficient and will result in a poor grade.

Note 2: For your project, you should either pass the array size (20) to the functions as a parameter or use a global constant to store it. Hard-coding the literal constant 20 in function definitions that receive the array as a parameter is poor style. It should be avoided.
