A student management system has to be developed for a University. The University demands the following conditions to be incorporated in the system to efficiently handle the student information, including student IDs, names, and marks of three different subjects. Develop the student management system to ensure flexibility and scalability for enrolling new students.The conditions are given as follows.Store the student IDs, name, and the marks of three different subjects for n students using dynamic memory allocation. Implement a user-defined function by passing the address to display the information of each student.

Solution

Sure, here is a simple implementation in C++:

#include<iostream>
using namespace std;

struct Student {
    int id;
    string name;
    int marks[3];
};

void display(Student *s, int n) {
    for(int i=0; i<n; i++) {
        cout << "Student ID: " << s[i].id << endl;
        cout << "Name: " << s[i].name << endl;
        cout << "Marks: ";
        for(int j=0; j<3; j++) {
            cout << s[i].marks[j] << " ";
        }
        cout << endl;
    }
}

int main() {
    int n;
    cout << "Enter the number of students: ";
    cin >> n;
    Student *s = new Student[n];
    for(int i=0; i<n; i++) {
        cout << "Enter student ID: ";
        cin >> s[i].id;
        cout << "Enter student name: ";
        cin >> s[i].name;
        cout << "Enter marks for 3 subjects: ";
        for(int j=0; j<3; j++) {
            cin >> s[i].marks[j];
        }
    }
    display(s, n);
    delete[] s;
    return 0;
}

This program first asks for the number of students. Then it dynamically allocates an array of Student structures. For each student, it asks for the ID, name, and marks for 3 subjects. After all the data is entered, it calls the display function to print out the information of each student. Finally, it deallocates the memory for the array of students.
