It's worth noting that simply calling getchar() will leave all
characters except the first one on the input stream if the user entered
any before pressing the "return" key which may not be desirable. In
such a case something like "while(getchar() != '\n')" may be preferred.

int c;

while( (c=getchar())!= '\n' && c!=EOF);
