    Re: Zeller's Congruence

    All the variables are already ints so using the floor() function is redundant. You also might want to look into putting some error guards in against invalid dates like February 29 in a non-leap year,...

    Re: Pointer Problem

    From what you posted earlier: Binary binarys[99]; This means you defined binarys as an array of Binary objects.

    Re: Pointer Problem

    I'm not sure it will get rid of your problems, but I noticed some design issues:

    1. You have using namespace in your header files. This should only be in your .cpp files. This can cause a myriad...

    Will you be performing any math on these? Is there a requirement for your numbers ever to be output as base-10?

  9. Re: Header files w/ c++, specifically data structures

    As of your last posting, there are several things wrong.

    It's not generally a good idea to test floating point numbers for primality because of round off error. To illustrate:

    Re: Error C2061

    Do all your header files have guards around them? By guard, I mean something like:


    #ifndef SOMEFILE_H
    #define SOMEFILE_H

    // all the usual header file stuff should go in here

    Re: Counting number of words + occurrences

    First of all, you are completely misusing switch-case.

    Example of how it should be used:

    {
    //do Something #1
    }
    else if(someVariable==2)

    Re: Modular Arithmetic

    If you need to get your head around this stuff, just make up some simple problems and work them by hand in -fraction- form.

    Do your loops so you iterate by row and by die number, with an array holding the roll values. Make a function that will draw a given row (but not every row) for a given roll value.
