    newbie questions

    I have a couple of questions. Call me an idiot if you wish.

    How do I declare a real number variable in C++?

    What is a function prototype and how is it used?

    What statement do you use to get data out of a value returning function?

    do you mean real as in positive integer?

    Code:
    unsigned int name;
    //or 
    int name;
    unsigned insures that it will not have a sign (positive)...

    >>What is a function prototype and how is it used?
    looks like this:
    Code:
    int function(int,char,float); //prototype
    ... //other stuff
    int function(int i,char a,float x) {...} //definition

    real as in the set of real numbers. The datatype is float (REAL*4) or double (REAL*8).
    All the buzzt!

    Simple assignment:
    Code:
    data = function();
    My best code is written with the delete key.
