Write a program that will analyze, for your class, the grades obtained by all the
students in any module test taken. The program will prompt the user to enter the
grade for each student. Valid grades are A, B, and C. The program calculates and
displays the total number of As, Bs and Cs. The user should be able to enter the
grades in uppercase or lowercase. You may assume there are only 10 students in
your class.
Your program must be modular. Write a function to read and total the grades and
another to print the results. A skeleton of the program is given below:
char grade; //-- global variables
int totalA, totalB, totalC;
int main()
{
readandTotalGrades();
displayTotals();
return 0;
}
