   Feb 18, 2013 · For historic reasons, it is possible to write return 0; to return from a function that has been declared as void, like so: void foo( /* arguments */ ) { /* do things */ return 0; } This does nothing, and the 0 (or whatever you put there) is thrown away.

   Code sample

   void foo( /* arguments */ ) {

     /* do things */

     return 0;
