What is the point of void?
I know "void" now as a tag or keyword, and vaguely understand that it has to do with voiding a return? but can this not also be done with = 0? I'm still getting my head around syntax, and just was curious if someone could offer me some insights on this one, please excuse my ignorance.

Void means not to return anything with the function.
0 is a value being returned, and usually that function will be an integer function.
A string function returns any string value. Same for other functions.
Void simply means there had nothing to return.
So if you call a void function, only the code is executed in that function. But if it is not void, a value is selected to be returned and can be assigned to a variable or used as an expression.

Why return 0 when you don't need to? :>
