Problem With Void
#include <iostream>
using namespace std;
void g();
int main() {
void g();
system ("PAUSE");
return 0;
}
void g(){
cout <<"hi there";
}
I'm just playing around trying to get the hang of void, but when I run it it doesn't output hi there. What am I doing wrong?

You need to call the function, like this:
This line of code:
means "there exists a function called g that takes in no parameters and returns none. It does not call the function, just states that the function exists.
While I'm here, this
is a terrible habit to get into.
g();This line of code:
void g();means "there exists a function called g that takes in no parameters and returns none. It does not call the function, just states that the function exists.

First of all, welcome to the forum. When posting code, please use [c0de][/c0de] tags (replaces 0's with o's).
Your problem is here:
remove the word void from inside the main when calling the function and it will work fine.
