Using function integer arguments with my C++ program -

i have little project do, i've created program when user types number, if it's or odd. used function. here's question:

how use integer arguments in function program? (my program does work, doesn't use integer arguments.)

instructions

write c++ function accepts integer argument, determines whether passed integer or odd, , displays result of determination. (hint: use % operator.)

make sure function called main(). test function passing various data it.

my code

#include <iostream>  using namespace std;  void oddeven() //my function   {      int num;      cout << "please enter number " << endl;     cin >> num;      if (num % 2)     {         cout << "it's odd" << endl;     }     else     {         cout << "it's even" << endl;     }     }  int main() //main program     {         oddeven(); //calling function     return 0; } 

sample program:

#include <iostream> using namespace std; void oddeven(int num/*num integer argument*/){     if (num % 2)     {      cout<<"it's odd"<<endl;     }     else     {       cout<<"it's even"<<endl;     } } int main() //main program {   int x;     cout<<"please enter number "<<endl;     cin>>x;     oddeven(x); //calling function      return 0;  }
