Question

C++ programming

Create a structure called Exam that includes exam ID (string), name of the subject (string), 

registration fee (double) and the number of students registered during a week (7 days) (int 

array). • Write a function called getExamDetails() which is the data type of Exam that reads the 

details of the Exam and store them in the variable of the Exam structure. 

Hint: Use the given function prototype as 

Exam getExamDetails (Exam e); 

• Write a function called calExamFee() which takes three parameters, registration fee for 

the exam, the number of students registered during a week (7 days) array and the size of the array. Find the total exam registration fee during the week and print the total exam 

registration to the screen. • Call the getExamDetails() and calExamFee() in the main function to print the following 

output as required.

Answer 1

#include <iostream>
using namespace std;
struct Exam {
    string examId;
    string subject;
    double fee;
    int registeredStudents[7];
};
Exam getExamDetails(Exam e) {
    cout << "Enter exam id: ";
    cin >> e.examId;


    cout << "Enter name of the subject: ";
    cin >> e.subject;
    
    cout << "Enter registration fee: ";
    cin >> e.fee;
    
    cout << "Enter a number of registered students during a week: \n";
    for (int i = 0; i < 7; i++) {
        cout << i + 1 << " - day: ";
        cin >> e.registeredStudents[i];
    }


    return e;
}
void calExamFee(double fee, int registeredStudents[], int length) {
    float Sum = 0;
    for (int i = 0; i < length; i++) {
        Sum += fee * registeredStudents[i];
    }
    cout << "Total exam fee: " << Sum << endl;
}
int main() {
    Exam e, temp;
    temp = getExamDetails(e);
    e = temp;
    calExamFee(e.fee, e.registeredStudents, 7);
    return 0;
}
