I predict a precision error

Use only whole numbers

What do you mean? :o

Yeah, what about it?

And he wants to show off a few select programs o:

Also I would like to invite you to show off your select few programs if you wish! :D

Note - if you don't feel like reading all this, just skip down to the code or leave if you like, this is my excited rambling

Anyways, just for the record, I use CodeBlocks as a compiler and it is delightful and I would recommend it to everybody (never mind the fact that I've never used anything else). I am learning through C++ For Dummies (I don't know if this is a quality book or not, but it's done a fairly good job of teaching me so far) and I have made a few programs on my own and a few programs that the book has told me to make.

I have included a WinRAR of every program I've made thus far, and the .exe is located in bin\debug I believe, so if you don't have a compiler to look at the code you can still see the results!

Also, if you do not have a compiler feel free to ask me for any source code, although I don't mean to flatter myself by saying y'all are indubitably enthralled by my delicious programming, I'm just saying the offer is there.

My favorite programs so far are the square number/cube number calculators. I could easily have done a simple loop saying, "multiply n by itself, output that, add one to n, repeat" but I used a new algorithm that I made all by myself for both!
You'll see in the source code.

Also here's a list of the ones that I made because CppFD told me so:

booltest
breakdemo
loops

Just as a warning, there are a few very stupid ones that I made early on (especially 'template', I don't know why I made that) like 'death' and 'counter' but alas, I'm too lazy/packrattish to delete them.

Anyways here is the source to the cubenumbers, squarenumbers, and collatzConjectureTotal:

I actually have a set of hypotheses which I have created: "If x = y - 1, then x² = y² - (2y - 1)" and "If x = y + 1, then x² = y² + (2y + 1)"

Code: (squarenumbers) [Select]

//Lists square numbers up to a user-defined point.

#include <cstdio>
#include <cstdlib>
#include <iostream>

using namespace std;

int main(int nNumberofArgs, char* pszArgs)
{
    //Set up all necessary variables.
    int square;
    int root;
    int additive;
    int limitdecision;
    int limit;

    //Define a few variables.
    square = 0;
    root = 0;
    additive = 1;
    cout << "Would you like a (0) root- or (1) square- limit? ";
    cin >> limitdecision;
    switch (limitdecision)
    {
        case 0:
            break;
        case 1:
            break;
        default:
            return 0;
    }
    cout << "Please enter the limit for the square numbers: ";
    cin >> limit;
    limit += 1;

    //Loop time!
    if (limitdecision == 0)
    {
        while (root < limit)
        {
            cout << square << " - " << root << endl;
            square += additive;
            root += 1;
            additive += 2;
        }
        system("PAUSE");
        return 0;
    }
    if (limitdecision == 1)
    {
        while (square < limit)
        {
            cout << square << " - " << root << endl;
            square += additive;
            root += 1;
            additive +=2;
        }
        system("PAUSE");
        return 0;
    }
}

I'll provide my equation as soon as I re-figure it out :(

If explanation is needed for anything, go ahead and ask me.
By the way you can tell that I have gotten more wise with my use of functions. It's very apparent in clock, less so in cct and nonexistant in mostly everywhere else

Anyways, please give me feedback and tips and perhaps ideas which are reasonable
And I would be happy to see some of your programs as well.

I wear slacks (or cargo pants, but I hate the notion of cargo pants) or jeans and collared button-down shirts. I despise logos. And a white undershirt if I can.
I generally forget what I'm wearing because I hardly ever actually pay attention to it, I just grab whatever two long-sleeved things I see.
I would wear nice shoes but they leave marks on the ground at school, and I wear ties occasionally.
What is that, fancy?

Smell them.
If it smells like your father, don't worry, he's just a transvestite, and not cheating on your step-mom.
Do it while your family's around, too, just in case you need a second opinion

You seem like you need something to be mad about. The increase in the amount of people with arthritis looks like about 50%. The actual population will not grow that fast.

I'm not mad at all friend, I was pointing out a flaw I saw.
But now I understand, I'm an idiot when it comes to that and I realise now that twenty years is nowhere near enough to raise the population 150 million

Correct me if I'm wrong at all.
See Nexus' and my exchange

By the year 2030, you say 67 million people will have it? From the current, what is it, like 46 million people today?
How am I supposed to take this fact seriously when you don't give me a percentage? A ratio of healthy to not healthy. Is that increasing, or is the population increasing and as a side effect that increases as well?
Say that five out of ten people in the year 1700 are cancerous. There are also only ten people alive. Say the population rises in one year by ten percent. So in 1710, somebody could go around saying "holystuffholystuff ten people have cancer as compared to the five people ten years ago!" but it's actually a meaningless statement because that's still 1:2 so it's note like it's any different.
It's the same thing here - give me a percentage so I know that the amount of people with arthritis isn't just increasing because the entire population is increasing. You seem to be trying to make it sound like a rising threat but if I'm right, and it's only increasing because the population is, it's not a rising threat at all.
