Question

Write a user-defined function that calculates the GPA. For the function name and arguments, use the following: The input argument g is a vector whose elements are the numerical values of the grades. The input argument h is a vector with the corresponding credit hours. The output argument GPA is the calculated GPA. Use the function to calculate the GPA for a student with the following record

Answer 1

Answer:

#include <iostream>

#include <vector>

using namespace std;

void calGPA();

vector<int> g;

vector<int> h;

int main(){

   char pushMore = 'y';

   int fg, fh;

   for (;;){

       if (pushMore == 'n'){

           break;

       } else{

           cout<< "Enter integer for grade: ";

           cin>> fg;

           cout<< "Enter integer for credit hours: ";

           cin>> fh;

           g.push_back(fg);

           h.push_back(fh);

           cout<< "Do you want to add more grade and credit hours? y/n: ";

           cin>> pushMore;

       }

   }

   calGPA();

}

void calGPA(){

   double total = 0, GPA;

   for (int i = 0; i < g.size(); ++i) {

        total +=  g.at(i) * h.at(i) ;

   }

   cout<< "The GPA is : "<< total/g.size();

}

Explanation:

The C++ source code above defines two vectors 'g' and 'h'. The latter holds the grades of a student while the former holds the credit hours for the subject taken. The void 'calGPA' function calculates and prints the student's GPA.
