Why does old code stay stuck in my console?

Thank you in advance for your responses!

I am using Dev compiler and compiled and ran my prog. I went back and changed some things, yet the changes don't show up, just the old code. What am I missing?

Code:

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

int addUP (int a, int b, int c)
 {return (a + b +c);}



 void main ()


 {
     //here is the first funciton call
   cout << "the first function is addition  " << addUP (3,4,12) << endl;

   int x = 12;
   int y = 25;
   int z = 140;

   //here is the 2nd call

   float average = addUP (x, y, z-20)/3;
   cout << " the average of "      << x << "  " << y << " and  " << z << " is  " << average;





  cin.get();

 return 0;
}

Considering that the code doesn't compile without errors, I expect that the reason you are getting the old output because your old code is the latest you have successfully compiled.

Don't feel bad about that, I've done it several times.

Edit: Did you by any chance change from C to C++ in this project?

Code:

void main ()
{
    ...

    return 0;
}

int main, not void main.

Code:

#include <stdio.h>

It would be more consistent (in C++) to use <cstdio> instead of <stdio.h>.

Code:

float average = addUP (x, y, z-20)/3;
cout << " the average of "      << x << "  " << y << " and  " << z << " is  " << average;

Very confusing to the user, you are displaying the average x, y, z-20 but you are telling them the average is of x, y, z. If they try to do the math themselves as an error check (based on what you've told them you are averaging), they're going to be confused.

Code:

#include <iostream>

...

cout << "the first function is addition  " << addUP (3,4,12) << endl;

...

cout << " the average of "      << x << "  " << y << " and  " << z << " is  " << average;

cout and endl are in the std namespace so you'd have to take that into account, so either:

1. Write using namespace std; somewhere after your #include statements.
2. Put using std::cout; using std::endl; statements somewhere before their use in your code.
3. Preface all of those items with std:: in your code.

However, stdio.h is not being referenced at all, so it could simply be removed altogether.
