How to clear the buffer for istreams?

[JUANDENT]

Hi,

what if I want to read only one character of input from the keyboard and want to use streams? so this:

char c;
cin >> x;

will read a character plus any other garbage the user entered. To clear the buffer I must now do this:

string str;
getline(cin, str);

Is there a cleaner one instruction way that would discard the values in the buffer?
