• strcpy
• strcat
• strcmp
• strstr
• strchr
• fgets

Specification

The program should repeatedly prompt the user to enter a string of no more than 20 characters. The program will end when the user types in DONE (all caps). Use fgets to get input from the user.

Because fgets leaves the newline character on the string, the program should trim off the newline by replacing it with the null character, effectively shortening the string. Use strchr to locate the newline.

The program will use the input to build up a longer string. You may assume this string will be no longer than 1000 characters. The user input is compared to the longer string and then takes action as follows:

• If the input is contained within the longer string, ignore it. Use strstr to perform the search.
• If the user input is less than the longer string (as indicated by the return value from strcmp), prepend the input onto the longer string with a space separating them.
• If the input is greater than the longer string, append it with a space separating them.

After each user input, display the longer string.

Sample Run

Here's a sample of how the program would work. I've shown user input in bold, just to help it stand out. Your program won't use any special typography.

Enter a string: hello
hello
Enter a string: world
hello world
Enter a string: bye
bye hello world
Enter a string: cat
bye hello world cat
Enter a string: worl
bye hello world cat
Enter a string: beep
beep bye hello world cat
Enter a string: bingo
beep bye hello world cat bingo
Enter a string: DONE
beep byte hello world cat bingo

Let's analyze this one input at a time.

1. User enters hello. Since this is the first sting entered, it is copied into the longer string.
2. User enters world. Because world comes after hello, it is appended onto the longer string.
3. User enters bye. This comes before hello world, so it is prepended.
4. User enters cat. This comes after bye hello world, and is appended.
5. User enters worl. This string is found within the longer one; no change to the longer string.
6. User enters beep. Since beep comes before bye hello world cat, it is prepended.
7. User enters bingo. This comes after beep bye hello world cat, and is appended.
8. User enters DONE. The longer string is displayed one last time and the program ends.

Please note that the program is not putting the words in alphabetic order. It's actually doing something simpler than sorting.

Program must be in C

Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate in two different arrays.

The program should then output each candidate’s name, the number of votes received, and the percentage of the total votes received by the candidate.

Your program should also output the winner of the election.

Example (Letters and numbers with underscore indicate an input):

Enter candidate's name and the votes received by the candidate.
Johnson 5000
Miller 4000
Duffy 6000
Robinson 2500
Asthony 1800

 Candidate    Votes Received   % of Total Votes
 ---------    --------------   ----------------
   Johnson       5000                 25.91
    Miller       4000                 20.73
     Duffy       6000                 31.09
  Robinson       2500                 12.95
   Asthony       1800                  9.33

Total Votes: 19300
The Winner of the Election is: Duffy

Write a Python program that simulates a restaurant ordering system where it stores multiple orders of a dish and the price for each order stored into a list. The program will then print the receipt which includes list of orders and their price along with the subtotal before tax, the tax amount, and the final total. Also include tip suggestions for 10%, 15% and 20%. Use the format specifiers to make the price line up and the tip only 2 decimal points.

Example:

Welcome to No 2. Kitchen

Order

Lt. Tso Chicken                 $ 17.50

Half Century Eggs            $   2.50

Durian ice cream               $   5.00

=========================

Subtotal                             $ 25.00

Tax (7%)                           $   1.75

=========================

Total                                  $ 26.75

Tip suggestion

10% : $2.67  

15% : $4.01

20% : $5.35

PLEASE ANSWER IN C

Assume that an int variable age has been declared and already given a value and assume that a char variable choice has been declared as well. Assume further that the user has just been presented with the following menu:

• S: hangar steak, red potatoes, asparagus
• T: whole trout, long rice, brussel sprouts
• B: cheddar cheeseburger, steak fries, cole slaw

(Yes, this menu really IS a menu!)

Write some code that reads a single character (S or T or B) into choice. Then the code prints out a recommended accompanying drink as follows:

If the value of age is 21 or lower, the recommendation is "vegetable juice" for steak, "cranberry juice" for trout, and "soda" for the burger. Otherwise, the recommendations are "cabernet", "chardonnay", and "IPA" for steak, trout, and burger respectively. Regardless of the value of age, your code should print "invalid menu selection" if the character read into choice was not S or T or B.

(Sort ArrayList) Write the following method that sorts an ArrayList:

  public static <E extends Comparable<E>>

void sort(ArrayList<E> list)

Write a program to test the method with three different arrays:

Integers: 2, 4, and 3;

Doubles: 3.4, 1.2, and -12.3;

Strings: "Bob", "Alice", "Ted", and "Carol"

What are the inputs and outputs for functional analysis and allocation? Explain how inputs are transformed to outputs. In what life cycle phase(s) is functional analysis and allocation performed?

python

Write a Loop class. The contents of a loop object are represented internally as a simple python list with the following additional instance variables:

loop - a python list containing the elements of the loop list

head - which stores the index of the first element of the loop list

current - which stores the index of the last element of the loop list

size - which stores how many actual elements are in the loop

max - which stores the max number of elements that can be in a loop

Note that current and head will be the same when the list is empty, and when the list contains a single element.

And methods:

__init__(self, max) - which constructs an empty loop object;

__str__(self) - which returns a string representing the loop object as described below;

add(element) - which adds the element to the end of the loop (i.e. at the position of current + 1)

empty() - which says whether there are any elements in the loop;

count() - which says how many elements currently are in the loop;

delete() - which returns the first item from the loop (i.e. at the position of head) and removes it from the loop;

max() - returns the max number of elements allowed in the loop.

__init__ initializes the empty locations in the loop list to None. Assume that max is always greater than the number of elements to be in the loop at any one time. When an element is being added to an empty loop, it always goes into the first location (index 0) in the loop list and head and current are reset to 0.

If an attempt is made to delete() from an empty loop then delete()  returns None. When an element is deleted from the loop its value is changed to None. Remember, your code needs to properly maintain the correct values of loop, head, current and size.

__str__ formats the loop object data as follows:

<max> <size> <head> <current> <loop list>

For example, after:

x = Loop(4)

x.add(1)

x.add(3)

x.delete()

print(x)

"print(x)" prints out:

4 1 1 1 [None, 3, None, None]

For example:

x = Loop(5)
print(x)

5 0 0 0 [None, None, None, None, None]

x = Loop(5)
x.add(3)
print(x)

5 1 0 0 [3, None, None, None, None]

x = Loop(3)
x.add(3)
x.add(2)
print(x)

3 2 0 1 [3, 2, None]

x = Loop(3)
x.add(3)
x.add(2)
x.delete()
print(x)

3 1 1 1 [None, 2, None]

x = Loop(3)
x.add(2)
x.add(5)
x.add(3)
x.delete()
x.add(7)
print(x)

3 3 1 0 [7, 5, 3]
