Create a C program that reads in text file AP7-1.txt and creates a comma separated file called AP7-2.csv. Calculate Gross Pay by multiplying hours worked by rate of pay. The first row in file AP7-2.csv should be headers for each data element. The data elements for output in the comma separated data file are employee ID number (int), hours worked (double), rate of pay (double) and gross pay (double). Your output file contents should look similar to: Emp ID

// Scanner class is imported so that the program can can user input

import java.util.Scanner;

// class Solution is defined

public class Solution {

//main method which begin program execution is defined

public static void main(String args[]) {

// Scanner object scan is defined to receive input fromkeyboard

Scanner scan = new Scanner(System.in);

// A prompt is display to the user asking for number of grade

System.out.println("How many grade do you want to enter");

// The user input is assigned to numOfGrade

int numOfGrade = scan.nextInt();

// An array of integer called gradeArray is declared

// it has numOfGrade as length

int[] gradeArray = new int[numOfGrade];

// for-loop that prompt the user to enter grade to fill the gradeArray

for(int i = 0; i < numOfGrade; i++){

System.out.println("Enter a grade: ");

int grade = scan.nextInt();

gradeArray[i] = grade;

}

// sun variable is declared and initialized to 0

int sum = 0;

// numOfFail is declared and initialized to 0

int numOfFail = 0;

// for-loop through the gradeArray that add all element

// it also increase the counter for numOfFail if grade is < 70

for(int j = 0; j < gradeArray.length; j++){

sum += gradeArray[j];

if (gradeArray[j] < 70){

numOfFail++;

}

}

// aveargeGrade is calculated

int averageGrade = (sum / numOfGrade);

// numOfFail is displayed to the user

System.out.println("Number of fail is: " + numOfFail);

// the averageGrade is also displayed.

System.out.println("Average grade is: " + averageGrade);

}

}

Explanation:

The code is well commented and written in Java.
