    Creating an Id # from first name last name and counter

    I need to use the first character from a first name and the first character from the last name and the counter number to create a student id. This is like BS-1. It must be used in several functions and different for each student. I know how to display it by using the cout<<fname[0]<<lname[0]<<"-"<<counter. I just don't know how to store this info into a variable because of the different data types.

    {
    
    		char lname[] = "lastname";
    		char fname[] = "firstname";
    		int counter = 1;
    		char id[10] = "";
    		
    		//format the id
    		sprintf(id, "%c%c-%d", fname[0], lname[0], counter);

    Student ID for class lab

    Thank you very much for your help. At first I had a problem but I went back and systematically recreated my program and got the "bugs" out.

    Your answer was so clear and easy to follow. Thanks again.
