    I don't understand what you need help with. Can you write a Hello World program? Do you know what a variable is? Do you know how to get input from the user? Do you understand how the math works?

    And you have to do operations on your matrix manually. So there is no method to say "add row 2 to row 3".

    You will want to look up arrays and 2 dimensional arrays in C.

    if ((a == x) || (a == z) || (b == x) || (b == z))

    I would also look into structures as that seems suited to what you are doing. It would let you do something like:

    TestItem.Name
    TestItem.ShieldCap
