Thread: good way of clearing excess input?

Here is the code i used to prevent input from overflowing to subsequent cin request. No matter what is typed in, only the first character is accepted. Everything after the first character is cleared until return/enter was pressed.

char letter, letter2;
cout << "Enter Letter: ";
cin >> letter;
for(; (cin.peek() != '\n') ;cin.ignore());

is this a good way to clear a buffer of unknown size?

tried that and i got an undefined variable error
i thought i had mentioned i use MSVC++ 6.0
*runs to his profile and adds his compiler*

This is non-ANSI, but it works for most:

Code:

#include <conio.h> 
...
/* clear keyboard buffer */
while(kbhit())
{
 getch();
}

It might be while(!kbhit())

how about for(char x; x != '\n';cin.get(x)); ?

basicly i want to mimic a dummy getline but not have to send it a length.
is there some kind of problem with using .peek() ?
