Write a program that declares an arbitrary function in a header file. The header file is called myheader.h Define this function inside the main program source file called source.cpp. The main function is also located inside a source.cpp file. Include the header into our source file and invoke the function.

myheader.h:

void myfunction();  //function declaration

source.cpp:

#include "myheader.h" //include the header

#include <iostream>

int main()

{

    myfunction();

}
