My first Math Program

[ksrocks333]

This is a simple program I made using some void functions and the math.h file thing. I did it in c++. If you want the source code tell me.
It's my first one, I'm looking for feedback, but it says all that in the program so yeah.
Download here:

my math program.zip

Tell me if that download link doesn't work.

I think I did this right, I put it in a winrar zip thing...XD

It should work...right?

I scanned it to make sure there weren't viruses:

Doesn't work. Nuff said.

[ksrocks333]

Doesn't work. Nuff said.

Can you please help me with what error your getting? Why does it work perfectly for me D:

Does it have to do with the fact I coded in C++?

Source Code:

#include <iostream.h>
#include <math.h>
using namespace std;

const double PI = 3.14159265;



void sum(double x, double y)
{
	cout<<x<<"+"<<y<<"="<<x+y<<endl;
}
void sub(double x, double y)
{
	cout<<x<<"-"<<y<<"="<<x-y<<endl;
}
void mult(double x, double y)
{
	cout<<x<<"*"<<y<<"="<<x*y<<endl;
}
void div(double x, double y)
{
	cout<<x<<"/"<<y<<"="<<x/y<<endl;
}
void mid(double x, double y)
{
	cout<<"The midpoint of "<<x<<" and "<<y<<" is: "<<(x+y)/2<<endl;
}
void grad(double x, double y)
{
	cout<<"Your grade of "<<x<<" out of "<<y<<" is: "<<(x/y)*100<<"%"<<endl;
}

EDIT. It's working on both my computers. One of which I've never downloaded any C++ programs before.

There is no error. Just doesn't start up because someone who created it didn't include the .dll's into the project. >x>

The .dll's? i'm not following? It's just supposed to come up as a command prompt thing with a blackground, no skin or buttons or anything. Just basic.

Also, if that's not what a dll is, I didn't add any dll's when I sent it to my other comp, so how did it work on there? D:

Pic of what it should look like:

[ksrocks333]

Chad it works... o.O
Even on my screwed up computer...
Make sure you have the C++ Runtime files...

@KsRocks You should program with VB / C# you have potential...

Oh great, now I know it works, that Eternal.

Oh, I have potential? This is good. Do you have any beginner VB guides that you used? Because I have no idea where to start.

[Chad]

You don't have to start with C#, or Vb.net. You can make programs in C++. No one really cares. We all use different languages here.

[ksrocks333]

C++ is "the most reknown"
C# is "simple and powerful"
VB is "the most powerful"

Just what I have heard...

And yes you have potential... I will post my Vid Tutorial Channel...

Thanks for the quotes ED. XD

What's the link to the vids?

[Chad]

i'd like to differ Eternal:

C++ is the most used and powerful.

C# is well known and powerful

VB is simple and powerful yet for beginners.
