    increasing variables

    Hi all,

    Just a quickie, I want to increase a variable by 3 each time it is ran in a loop;

    I know variable++ increases by one each time, how would i get it to increase by 3??

    Thanks guys

    boontune - You may already know this... but new programmers can be confused by this:

    MyVariable = MyVariable + 3 ; // Bad in math. OK in programming!

    In programming, this is an ASSIGNMENT (Assigning a new value to MyVariable). it's not an equation!

    For simple operations polymorphic OOP's example is the standard "C++ way" of doing it. But, it is common to see the left-side variable repeated on the right side of the assignment statement.
