    I printed it out, and fixed it to a wall
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    A bit more fixing:
    Code:
    #include <iostream>
    #include <iomanip>
    
    using namespace std;
    <rest of code>
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    Do you understand what a union is? You likely don't need to use one.

    For a start you can get rid of the '.h' at the end of the header file declarations, no need for it when coding in C++.

    I assume you want to display the values stored in the variables you created?

    Edit - oh btw the correct spelling is 'Program'

    Oh oh! Me too!

    Code:
    A.phone  = 0x00000000;    // This is pointless.
    A.phone  = 0x11223344;
    A.number = 0x5555;
    
    B.phone  = 0x00000000;    // This is pointless.
    B.phone  = 0x11223344;
    B.number = 0x5555;

    This is going nowhere.
    I'm putting it out of my misery.
