Answer to Question #317965 in C++ for jane

Question

Les assume you create a system which asks the user for the number of students and the

number of test scores per student. A nested inner loop, should ask for all the test scores for one

student, iterating once for each test score. The outer loop should iterate once for each student

and take student name as input. After taking input for 3 test scores, calculate average for each

student. Take 3 test scores and 4 students.

Note: use do-while loops

Answer 1

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


int main() {
    const int NUM_STUDENTS = 4;
    const int NUM_TESTS = 3;


    int num_student = 1;
    do {
        cout << "Enter data for the " << num_student << "th student" << endl;


        int sum = 0;
        int num_test = 1;
        do {
            int score;
            cout << "Test " << num_test << ": ";
            cin >> score;
            sum += score;
            num_test++;
        } while (num_test <= NUM_TESTS);


        double avg = sum / NUM_TESTS;
        cout << "Average score is "
             << fixed << setprecision(2) << avg << endl << endl;


        num_student++;
    } while (num_student <= NUM_STUDENTS);


    return 0;
}
