// the account and add a deposit to the account and the user can add interest to the account 
// which is calculated at 1.67% and the account number used to setup the account is 00112280

Hi

I have a few problems on the code for the bank account project, it will be appreciated if you can have a look for me:

Problem 1:

#include "stdafx.h"
In c++ the word include in the above line is highlighted in red.

Problem 2:

} // End of switch statement

} // End of loop

void open_account()// allocate account number, get initial balance and confirmation message that account has been
// created

{

In c++ the bracket next to // End of loop is highlighted in red.

Problem 3:

_getch()

}

void display_account_details()

In c++ the bracket above void display_account_details is highlighted in red.

Problem 4:

void main()
}
display_main_menu();
}

In c++ the both the opening and closing bracket is highlighted in red and also the ; after display_main_menu();

Thanks
