You don't HAVE to in most cases. They help to avoid compile-time issues
and are required for referencing functions in multiple object files.
int B()
{
A();
}
int A()
{
// Assume C() is defined in a different file.
C();
}
Prototypes are a good habit to get into though. You will quickly get
the hang of copy, paste, jump to the end of the line, tack on a semi-colon.
