Declarations can be used as place holders for definitions placed latter on in the programs.
Parameter names can be given, but are not needed, within declarations.

#include <iostream>
using namespace std;

void f( int );

int main()
{
   f( 5 );   f( 66 );
   return 0;
}

void f( int x )
{
    cout << x << endl;
}
