And the difference between gets/scanf and fgets is that gets(); and scanf(); only scan until the first space ' ' while fgets(); scans the whole input. (but be sure to clean the buffer afterwards so you wont get an overflow later on) c - Disable warning: the `gets' function is dangerous in GCC through ....

The gets function is used for returning zero or more characters from the standard (console) input.
