15.1 File IO Warm-up

For this exercise, you will receive two string inputs, which are the names of the text files. You need to check if the input file exists. If input file doesn't exist, print out "Input file does not exist."

You are required to create 4 functions:

void removeSpace (ifstream &inStream, ofstream &outStream): removes white space from a text file and write to a new file. If write is successful, print out "Text with no white space is successfully written to outFileName."

int countChar (ifstream &inStream): returns number of character in input file.

int countWord(ifstream &inStream): returns number of words in input file.

int countLines(ifstream &inStream): returns number of lines in input file.

After calling each function, you have to reset the state flags and move the stream pointer to beginning of file. You can do that by closing and re-opening the file, or by calling member functions:

inStream.clear(); inStream.seekg(0);

Example:

Input: input.txt output.txt

Output:

Text with no white space is successfully written to output.txt.

Number of characters is: 154

Number of words is: 36

Number of lines is: 10

here is the code in C++:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

void removeSpace(ifstream &inStream, ofstream &outStream);
int countChar (ifstream &inStream);
int countWords(ifstream &inStream);
int countLines (ifstream &inStream);

int main()
{
string input, output;
cin >> input >> output;

ifstream inStream(input);
ofstream outStream(output);

if(inStream.fail())
cout << "Input file does not exist.\n" ;
else
{
removeSpace(inStream, outStream);
cout << "Text with no white space is successfully written to outFileName.\n";
inStream.clear();
inStream.seekg(0, inStream.beg);

cout << "Number of characters is: " << countChar(inStream) << endl;
inStream.clear();
inStream.seekg(0, inStream.beg);

cout << "Number of words is: " << countWords(inStream) << endl;
inStream.clear();
inStream.seekg(0, inStream.beg);

cout << "Number of lines is: " << countLines(inStream) << endl;
inStream.close();
}

outStream.close();

return 0;
}

Write a working C++ program to ask the user for a set of grades which are to be stored in an array in increasing sequence. The user must first provide the number which represents the count of all grades to be provided. For example, if there will be 10 grades, the user is first prompted to provide the number 10. Subsequently, each grade is provided, one at a time. Allow for a maximum of 30 grades in defining the array. When all the grades have been sorted properly, print them all, along with the average.

Process the array using a function which is invoked from the main body of the program. The main body asks for the count of grades and then invokes the grade sequencing function.

You must write in proper C++ syntax and actually execute the program to ensure it works properly.

Create a C# console application (do not create a .NET CORE project) and name the project. Generate two random integers, each between 1 and 50, that you will be adding together to test the user's ability to perform the addition operator. Display the numbers in the console, such as:

            7 + 22 = ?

Once the user provides their answer, check to see if it is correct and if not, tell them sorry, please try again. If their answer is correct, congratulate them on getting the right answer.

Python

Write a program that loops, prompting the user for their full name, their exam result (an integer between 1 and 100), and then writes that data out to file called ‘customers.txt’. The program should check inputs for validity according to the following rules:

  • First and last names must use only alphabetical characters. No spaces, hyphens or special characters. Names must be less than 20 characters long.
  • Exam result (an integer between 1 and 100 inclusive)

The file should record each customers information on a single line and the output file should have the following appearance.

Nurke Fred 58

Cranium Richard 97

Write a second program that opens the ‘customers.txt’ file for reading and then reads each record, splitting it into its component fields and checking each field for validity.

The rules for validity are as in your first program, with the addition of a rule that specifies that each record must contain exactly 3 fields.

Your program should print out each valid record it reads.

The program should be able to raise an exception on invalid input, print out an error message with the line and what the error was, and continue running properly on the next line(s).

Create a C# console application (do not create a .NET CORE project) and name the project TuitionIncrease. The college charges a full-time student $12,000 in tuition per semester. It has been announced that there will be a tuition increase by 5% each year for the next 7 years. Your application should display the projected semester tuition amount for the next 7 years in the console window in the following format:

            The tuition after year 1 will be $12,600.

Note: The number is in the output and the format of the tuition amount is currency with 0 decimal places

Create a C# console application (do not create a .NET CORE project) and name the project TimeToBurn. Running on a particular treadmill, you burn 3.9 calories per minute. Ask the user how many calories they wish to burn in this workout session (this is their goal). Once they tell you, output on the console after each minute, how many calories they have burned (e.g. After 1 minute, you have burned 3.9 calories). Keep outputting the total amount of calories they have burned until they have met their goal.

pseudocode The main( ) program passes these integer values as arguments to the findMax( ) method for further processing. The main program receives one result back from findMax( ) method and displays the maximum of these three integer values. The findMax( ) method simply receives three integer values from the main program and finds the maximum of three integers and returns one value back to the caller (in this case the main application).

Using JAVA

The following code is able to read integers from a file that is called "start.ppm" onto a 3d array called "startImage".

Implement the code by being able to read from another file (make up any file name) and save the data onto another 3d array lets say you call that array "finalImage".

The purpose of this will be to add both arrays and then get the average

Save the average onto a separte 3darray,lets say you call it "middlearray"

Then add startImage and middlearray and get the average then save it to another array called "fourtharray"

Then add finalImage and middle array and get the average then save it to another array called "fiftharray".

Print all 5 arrays

import java.util.Scanner;
import java.io.*;

public class P1
{

public static void main(String[] args) throws IOException
{
final int ROW=267;
final int COL=400;
File file= new File("start.ppm");
Scanner inputF= new Scanner(file);

int[][][] startImage= new int[ROW][COL][3];
  
int row=0, col=0;
int line=1;
while (inputF.hasNext())
{
if(line<=4)
{
inputF.nextLine();
line++;
}
else
{
line+=3;
if (col< COL)
{
startImage[row][col][0]=inputF.nextInt();
startImage[row][col][1]=inputF.nextInt();

Use Boolean algebraic laws to prove the following equivalences:

  1. [ ( p → q ) ∨ ( p → r ) ] ⟷ [ p ⟶ ( q ∨ r ) ]
  2. ¬ [ ¬ ( p ∧ q ) ∧ ( p ∨ q ) ] ↔ [ ( p → q ) ∧ ( q → p ) ]

If you are able to explain some of the thought process behind the problems, that would be amazing. Thanks
