Answer 1

#include <iostream>
#include <iomanip>
using namespace std;

double GetAverage(const char *name, int n) {
    int total=0, mark;
    double avg;

    for (int i=0; i<n; i++) {
        cout << name << i+1 << ": ";
        cin >> mark;
        total += mark;
    }
    avg = static_cast<double>(total) / n;
    cout << "Average: " << avg << endl;;

    return avg;
}


int main() {
    double quiz_avg;
    double lab_avg;
    double assign_avg;

    cout << "Class Participant" << endl;
    quiz_avg = GetAverage("Quiz", 4);
    lab_avg = GetAverage("Lab", 4);
    assign_avg = GetAverage("Assignment", 4);

    double class_part = 0.4 * (quiz_avg + lab_avg + assign_avg) / 3;
    cout << "Class Participation: " << fixed << setprecision(2) << class_part << endl;

    int exam_mark;
    cout << "Prelim Exam: ";
    cin >> exam_mark;
    double exam = 0.6 * exam_mark;
    cout << "% " << exam << endl;

    double grade = class_part + exam;
    cout << "Prelim Grade: " << grade << endl;

    cout << "Remarks: ";
    if (grade >= 75) {
        cout << "PASSED" << endl;
    }
    else {
        cout << "FAILED" << endl;
    }
