/*                          Returning Values 

The return statement terminates the execution of a function and returns control to the calling function usually main(). 

The following program demonstrates functions returning a value by passing 3 floating point numbers and calculating the average and returns the answer.

#include <stdio.h>
float gradeAvg(float test1, float test2, float test3);

main()
{
    float grade1, grade2, grade3;
    float average;

    printf("What was the grade on the first exam? ");
    scanf(" %f", &grade1);

    printf("What was the grade on the second exam? ");
    scanf(" %f", &grade2);

    printf("What was the grade on the final exam? ");
    scanf(" %f", &grade3);

    // Now we pass the 3 grades to the function and return the average

    average = gradeAvg(grade1, grade2, grade3);

    printf("\nWith those three test scores, the average is %.2f", average);

    return 0;
