C++

BREAK UP THE FOLLOWING C++ PROGRAM INTO 3 VOID FUNCTIONS.

Function and output requirements: One function does input. One function computes the course GPA points in the array. One function computes the GPA. One function outputs to a file the student’s name, a table of the courses, grade received, course credits and GPA points earned, and finally, the student’s semester GPA.

Solution

Hi, I have added all required functions.

Please test this program with data and let me know in case of any issue.

#include <iostream>
