(Beginner here) why does cout not work with functions?

Question

I am trying to make a function that writes something in the console, but I am unable to make that work. Here is the code:

#include <iostream>
using namespace std;
void test () {
	cout<<"test";
}
int main () {
	int test ();
}

Expected result: the word "test" appears in the console
Observed result: the console returns 0 without anything appearing in the console.

What I have tried:

Switching from int to void or changin the order of the functions seems to do nothing, and I have no idea of what the problem could be.

I would say your code does not compile.
Try this ;)

C++

#include <iostream>
using namespace std;
void test () {
	cout<<"test";
}
int main () {
    // int test ();
	test ();
}

Calling a method with a return value (int in that example) should be int result= test() . But in case the method does not have a return like void test() value you simply call it with test();.
[Edit]
Even a method returns e.g. int, but you are not interesting on that value you can invoke the method with test() [/Edit]

I hope it helps.
