Because it could be an error or not, depending on what standard are you using.
In C89 a function without a prototype is implicitly declared.
This is not true if your're working in C99.


Using cc with -Wimplicit as option will show you warnings about
implicit function declarations..

Using cc with -Wall as option is usually good practice....
