Code

#include <iostream>
using namespace std;

// Function to convert grade to grade points
float getGradePoint(char grade) {
    switch(grade) {
        case 'A': return 10;
        case 'B': return 8;
        case 'C': return 6;
        case 'D': return 4;
        case 'F': return 0;
        default: return 0;
    }
}

int main() {
    int semesters;
    cout << "Enter number of semesters: ";
    cin >> semesters;

    float totalCGPA = 0;

    for(int s = 1; s <= semesters; s++) {
        int subjects;
        cout << "\nEnter number of subjects in Semester " << s << ": ";
        cin >> subjects;

        float totalCredits = 0, totalPoints = 0;

        for(int i = 1; i <= subjects; i++) {
            int credit;
            char grade;

            cout << "\nSubject " << i << ":\n";
            cout << "Enter credit hours: ";
            cin >> credit;

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

            float gradePoint = getGradePoint(grade);

            totalCredits += credit;
            totalPoints += gradePoint * credit;
        }

        float GPA = totalPoints / totalCredits;
        cout << "\nGPA of Semester " << s << " = " << GPA << endl;

        totalCGPA += GPA;
    }

    float CGPA = totalCGPA / semesters;
    cout << "\nFinal CGPA = " << CGPA << endl;

    return 0;
