Thread: I need help.

How do I display the id number that I input to case 2?

Code:

#include <iostream.h> 
#include <windows.h>
#include <stdlib.h>


int studentID( int n[], int maxStudent);
int regID;






int main()
{
    int mainMenu;
    int studentlist;
    int Exams;
    int Reports;
    
    
    
    system ("COLOR 3F");






    cout << "\t\t\tWelcome to Student Record Program"<<endl<<endl<<endl;
    cout << "\t\tM A I N  M E N U\n";
    cout << "\t\t_____________________________________"<<endl;
    cout << "\t\t(1) - STUDENT LIST " <<endl;
    cout << "\t\t(2) - EXAMS " <<endl;
    cout << "\t\t(3) - REPORTS " <<endl;
    cout << "\t\t(4) - EXIT FROM THE PROGRAM "<<endl;
    cout << "\t\t_____________________________________"<<endl<<endl;
    cout << "\t\tEnter here ===>> ";
    cin >> mainMenu;












switch(mainMenu)
