How to write multiple c++ files?

Here is my try:

Code:

//print_bin.h:
void print_bin ();

Code:

//print_bin.cpp:
#include<iostream>
using namespace std;
void print_bin () {
         cout<<"abc";
}

Code:

//bitwise.cpp
#include "print_bin.h"
#include <iostream>
using namespace std;
int main () 
{
   int i;
}

[root@localhost fifth]# g++ bitwise.cpp print_bin.cpp -o bit_print
[root@localhost fifth]# ./bit_print
[root@localhost fifth]#
It can be compiled with no error, however, why the program don't output abc that is I want to do?
Thank you.

You have to call the function print_bin() in the main() of your program

Code:

#include"print_bin.h"
#include<iostream>
using namespace std
int main()
{
int i;
print_bin();
}

When you include a file that you have made all the functions in that file accessible and not that you are calling them.
