Explanation / Answer

Solution to given problem is provided below. Comments are added in code for explanatory purpose. Sample execution output is also given below.

File: gpa.cpp

#include <iostream>
#include <iomanip>

using namespace std;

// Return grade points for given grade
float convertGradeToGradePoints(char grade) {
switch (grade) {
case 'A':
return 4.00;
case 'B':
return 3.00;
case 'C':
return 2.00;
case 'D':
return 1.00;
case 'F':
default:
return 0.00;
}
}

int main() {
string courseName;
int numCredits;
char grade;
string repeat;

int totalCredits = 0;
float totalGradePoints = 0;
float gpa;
  
do {

// Read course name
cout << "Enter a course name: ";
cin >> courseName;

// Ignore until new line
cin.ignore(256,' ');

// Read number of credits
cout << "Enter number of credits: ";
cin >> numCredits;

// Read grade
cout << "Enter your grade (A, B, C, D, F): ";
cin >> grade;

// Read if student want to add more courses
cout << "Continue ('Yes' or 'No')? ";
cin >> repeat;

// Update total credits and total grade points
totalCredits += numCredits;
totalGradePoints += numCredits * convertGradeToGradePoints(grade);

} while (repeat.compare("Yes") == 0);

// Compute GPA
gpa = totalGradePoints / totalCredits;

// Output total grade points, total credits and GPA
cout << "Total grade points: " << std::setprecision(0) << std::fixed << totalGradePoints << endl;
cout << "Total credits attempted: " << totalCredits << endl;
cout << "Your GPA is " << std::setprecision(2) << std::fixed << gpa << endl;

return 0;
}

Sample Execution Output:

$ g++ gpa.cpp
$ ./a.out
Enter a course name: CMPSC 101
Enter number of credits: 3
Enter your grade (A, B, C, D, F): A
Continue ('Yes' or 'No')? Yes

Enter number of credits: 3
Enter your grade (A, B, C, D, F): B
Continue ('Yes' or 'No')? Yes
Enter a course name: ACCT 50
Enter number of credits: 1
Enter your grade (A, B, C, D, F): D
Continue ('Yes' or 'No')? No
Total grade points: 22
