Another program with more problems.

Ok, this is a different program and I can't seem to get this program to work. It's the function that wont work.

Code:

#include <iostream>
using namespace std;


int Add(int firstNUM, int secondNUM)
    {
    cout <<"Tn the function now!" <<endl;
    cout <<"The number " <<firstNUM << " and the number " <<secondNUM << " will now be added together" <<endl;
    cout <<firstNUM <<" + " <<secondNUM <<"is the equation." <<endl;
    return (firstNUM+secondNUM);
    }
int main()
{
int firstNUM, secondNUM, sumNUM;

cout <<"This is a function program, just checking to see how good I know functions." <<endl;
cout <<"Enter a number" <<endl;
cin >>firstNUM;
cout <<"Enter another number" <<endl;
cin >>secondNUM;
sumNUM = Add(firstNUM,secondNUM);
cout <<Add();

system("pause");

return 0;
}

Can anyone help me out here?

try:

cout << Add(firstNUM,secondNUM) << endl;

Code:

#include <iostream>
using namespace std;


int Add(int firstNUM, int secondNUM)
{
  cout << "Tn the function now!" << endl;
  cout << "The number " << firstNUM << " and the number " << secondNUM << " will now be added together" << endl;
  cout << firstNUM << " + " << secondNUM << "is the equation." << endl;
  return (firstNUM+secondNUM);
}

int main()
{
  int firstNUM, secondNUM, sumNUM;

  cout << "This is a function program, just checking to see how good I know functions." << endl;
  cout << "Enter a number" <<endl;
  cin >> firstNUM;
  cout << "Enter another number" << endl;
  cin >> secondNUM;
  sumNUM = Add(firstNUM,secondNUM);
  cout << sumNUM;

  return 0;
}

Calling cout << Add() is the error...

Thank You both!
