CPP / C++ / C Code:

void add_user(void)
{
int go = 1;
char ask;
while(go == 1)
	{
		if (entered == MAX_USER)
		{
			cout << "\tUser entry is full!";
			go = 0;
		}
		else
		{
			cout <<"Enter Pin:" << endl; 
			cin >> user_pin[entered];
			cin.ignore(2,'\n');

			cout <<"Enter Start Time:" << endl; 
			cin >> user_starttime[entered];
			cin.ignore(2,'\n');
			
			cout <<"Enter Stop Time:" << endl; 
			cin >> user_stoptime[entered];
			cin.ignore(2,'\n');
			
			cout <<"Enter Expiry Date:" << endl; 
			cin >> user_expirydate[entered];
			cin.ignore(2,'\n');
			entered++;
			
			cout << "\tContinue with next entry [Y/N]?";
			cin >> ask;
			cin.ignore(2,'\n');
			cout << endl;
			if( ask == 'N' || ask == 'n')
			{
 		display_menu();			                          }
	
		}

Neither do we. No one explained it to us. Please read the Guidelines. Pay close attention to #1, #2, #3

Before posting, make sure that you put [c++] and [/c++] tags before and after your code. Otherwise, we can't read it, and we can't be of much help.

I am not sure what you are asking. You will need to more specific.

Example Question:
When I am done in my function "add_user" how can I get back to the calling function.

One Solution :
If you call "return" from a void function(like add_user) that will cause the function to stop execution and return to the calling function
(cardid_configuration).

So if you change this "if" statement from "add_user",

CPP / C++ / C Code:

if( ask == 'N' || ask == 'n')
   {
      display_menu();  
   }

to,

CPP / C++ / C Code:

if( ask == 'N' || ask == 'n')
   {
      return;  
   }

You will end up back in "cardid_configuration".

For someone that would like help, you seem to be ignoring some of that help, which, I repeat, is:

Let's get the other guidelines too, as I mentioned before you. He needs more that just code tags...
