void

what does the void command mean and how do you use it in programming?
Sorry for being such a noobie ^^;

Here is an example of when void would be used:

Code:

#include <iostream>

using namespace std;

void example()  // example is a function, but I have voided it so it returns nothing to main

int main()
{

example(); // this calls the function example

return 0; 
}

void example() // you can now use the function as main has called it
{

code for exapmle would go here{
return; // return nothing to main as example is void
}

this is just one example of it's use in a function, but void has one golden rule:

Never use the command 'void main()' as main must ALWAYS return an integerger or int

void means no type. As in, no return type for a function, so it doesn't have to return anything. Or a void pointer can be casted into a pointer of any other type.
