hi gang,

ok, here's the general code:

	do
	{
		char choice;
		printf( "Enter 'a', 'q', or 'f': " );
		scanf( "%c" &choice );
		printf( "Your choice was: %c", choice );
		if( choice == 'a' ) ...
		if( choice == 'f' ) ...
	 }while (choice != 'q' )
	printf( "Finished" );

the problem is when i go through this loop it goes through it twice
because on scanf() it takes the char as input AND the newline (ie '\n').

so an example output would be:

Enter 'a', 'q', or 'f': e
Your choice was: e
Enter 'a', 'q', or 'f':       <- the input is the newline from the "e"
Your choice was:              <- output is the newline ("\n")

Enter 'a', 'q', or 'f': q
Finished

now how can i have the input be JUST the "e" and not the newline "\n"?
thanks for anyhelp, this problem has given me much fuss.

russ
