Math program (small) compiling and math errors .

Hey guys im trying to learn C++.

This was a simple program i made while reading C++ For dummies

CPP / C++ / C Code:

#include <cstdlib>
#include <iostream>
#include <windows.h>

using namespace std;


int BigDog(int KibblesCount) {
     int NumCount;
    cout << "How many kibbles should we feed the doggie?" << endl;
    cin >> KibblesCount;
     cout << "I'm a lucky dog" << endl;
     cout << "I have " << KibblesCount<< " doggie treats" << endl;
          cout << "RUFF RUFF RUFF" << endl;
          KibblesCount = NumCount;
          while(NumCount > 0) {
                cout << "Num num num num thanks!" << endl;
                NumCount--;
                }
               cout << "Ruh Roh! I Are All Out!" << endl;
}
    
int main(int argc, char *argv[])
{
    BigDog(KibblesCount);
    system("PAUSE");
            return 0;
}

First it said, KibblesCount is undeclared. So i put

Code:

 Int KibblesCount

at the top.

Then, when i put an integer to basically "Feed the dog" it spammed it then exited.

What this prog does
--------------------
You experts know but for the lazy, im trying to make it so when you enter an integer, it will say Num Num Num that many times.

Thanks in advance

What is spammed? you mean endless loop?
You have:
while(NumCount > 0)

What do you think NumCount's value is?

You can see by printing it. Just add to the exsiting print:
cout << "Num num num num thanks! NumCount=" << NumCount << endl;

Try that and see it you understand better what is wrong.

also
windows.h is not being used in your program , don't include it.

The only thing you need cstdlib.h for is the system() function in.
system("PAUSE");

PAUSE is window specific. You can pause C++ style instead:
cin.get(); // waits until return is pressed

then you can loose #include <cstdlib.h> too.
(you'll also learn something else about user input , you might need two cin.get(); 's. Why? (more will be revealed): )

So you'll just have:
#include <iostream>
using namespace std;
