Used for when you can use def function(): The sacred syllable (foo mani padme hum); Void foo () { } void foo (void) { } is there a difference between these two?
I've always wanted to know what the foo, bar, baz, etc. Consider these two function definitions: I hope this qualifies as a programming question, as in any programming tutorial, you eventually come across 'foo' in the code examples.
