Define a function named average_grade.This function returns a double and has four double arguments,test1,test2,test3,test4.The return value should be the average,or arithmetic mean of the four arguments.Be sure to include a comment that tells briefly what the function does.

Question

Quizplus · Accepted Answer

The Answer is // returns arithmetic mean of the arguments test1 - test4
double average_grade (double test1-,double test2,
double test3,double test4)
{
double average;
average = (test1 + test2 + test3 + test4)/ 4;
return average;
}
This slightly more terse definition is sufficient:
//returns arithmetic mean of the arguments test1 - test4
double average_grade (double test1,double test2,
double test3,double test4)
{
return (test1 + test2 + test3 + test4)/ 4;
}
