You do not use the type "int" when you are using the - operator:

	NumberThree = int NumberOne - int NumberTwo;

is wrong syntax.
you need instead:

	NumberThree = NumberOne - NumberTwo;

but for this to work, the function ThirdNumber(int) needs to take NumberOne
and NumberTwo as parameters.
so you need to put

	ThirdNumber(int,int,int);

as the definition. and in the main function, you call it like this:

	ThirdNumber(NumberThree,NumberTwo,NumberOne);

you do not call functions with their return type and argument types either:

	int FirstNumber(int NumberOne);

is wrong syntax (this is the call, not the definition).
you need instead:

	FirstNumber(NumberOne);

you also need to use references, because the data you get from the user does
not survive the local scope of the function.
maybe i just write out your program correctly, removing syntax errors (but
not improving code):

#include <stdio.h>
#include <iostream>
#include <string>

/*
This program in designed to take input from the user,
in the form of a number and compute the output.
The program is then to display the output back to the user.
*/

int FirstNumber(int&);   // Function Definitions
int SecondNumber(int&);  // Function Definitions
int ThirdNumber(int,int,int); // Function Definitions

// FirstNumber Function
int FirstNumber(int NumberOne)
{
  cout << "Enter how much money you had this morning $";
  cin >> NumberOne;
}

// SecondNumber Function
int SecondNumber(int NumberTwo)
{
  cout << "Enter how much money you have now $";
  cin >> NumberTwo;
}

// ThirdNumber Function
int ThirdNumber(int NumberThree, int NumberTwo, int NumberOne)
{
  NumberThree = int NumberOne - int NumberTwo;
  cout << "You have spent $" << NumberThree << " dollars today " << endl;
}

// Main Function
int main(int argc, char *argv[])
{
    int NumberOne;
    int NumberTwo;
    int NumberThree;

    FirstNumber(NumberOne);
    SecondNumber(NumberTwo);
    ThirdNumber(NumberThree,NumberTwo,NumberOne);

    system("PAUSE");
    return 0;
}

Gudday All,

    I have a small problem which I cant seem to find the answer to. I was
hoping that someone could help. I am just beginning to learn c++, so the
code is not to complex. My problem lies in the compilation process. I am
unsure as to how to fix the compilation error.

Thanks to everybody.
Have a good one.
John

Here is the compilation error.

32 six.cpp parse error before `-'

And here is my source code :-

#include <stdio.h>
#include <iostream>
#include <string>

/*
This program in designed to take input from the user,
in the form of a number and compute the output.
The program is then to display the output back to the user.
*/

int FirstNumber(int NumberOne);   // Function Definitions
int SecondNumber(int NumberTwo);  // Function Definitions
int ThirdNumber(int NumberThree); // Function Definitions

// FirstNumber Function
int FirstNumber(int NumberOne)
{
  cout << "Enter how much money you had this morning $";
  cin >> NumberOne;
}

// SecondNumber Function
int SecondNumber(int NumberTwo)
{
  cout << "Enter how much money you have now $";
  cin >> NumberTwo;
}

// ThirdNumber Function
int ThirdNumber(int NumberThree)
{
  NumberThree = int NumberOne - int NumberTwo;
  cout << "You have spent $" << NumberThree << " dollars today " << endl;
}

// Main Function
int main(int argc, char *argv[])
{
    int NumberOne;
    int NumberTwo;
    int NumberThree;

    int FirstNumber(int NumberOne);
    int SecondNumber(int NumberTwo);
    int ThirdNumber(int NumberThree);

    system("PAUSE");
    return 0;
}
