C++ Recursion Quiz : Some Light Relief...

Can you figure out what 'dosomething' does without a compiler int dosomething(int numberone) { if(numberone == 1) {return 1;} if(numberone >= 1) { return (numberone * dosomething(numberone-1)); } } Just a little light relief! Regards, Ozz. Edited by - Ozz on January 27, 2001 2:34:52 PM

Just being picky, here. I''ve not tried compiling it, but wouldn''t it fail as not all control paths actually return a value?

E.g. If you called dosomething(-2)...

You''d get stuck in an infinite loop, for sure, but it would still compile. dosomething(-2) _does_ have a return value, it''s doSomething(-3) + doSomething(-4).

anyway my point is that it would _not_ fail to compile.
