Why the value of a function is 1?

Question

I just learn C++ and i don't understand what is the used of return even with the help of google, here is a code that returns the value 9 to returnvalue but the output of the code below is 1 why is this so won't 9 = returnvalue? If not then can i return any value back to my function will that affect anything?

#include <iostream>
using namespace std;
int returnvalue(){
    return 9;}
int main(){
    cout<<returnvalue;}

@Eljay It works thankyou so much – user93228 Dec 12 '17 at 18:41 — user93228, Dec 12 '17 at 18:41

You're feeding std::cout a funtion pointer to returnvalue instead of calling it, to call it add ():

cout<<returnvalue();
