Need a challenge

Hey guys,

I'm kind of new to programming, and i set my self a task to make a program that find 25% of any number, well i did it in a couple of hours using the following code

Code:

---

#include <iostream>

using namespace std;

float main()
{
 float num1;


 {
 cout <<"this a simple percentage program";
 cout <<endl;
 cout <<"to find 25% of any number";
 cout <<endl;
 }
 float x = 10;
 while ( x = 10 ){
 cout <<"insert the number you want to find 25 percentage of:  ";
 cin >> num1;
 cout <<"the percentage of:  "<< num1 << endl;
 cin.get();
 cout <<"would be: "<< 25 * num1 / 100 << endl;
 cin.get();
 x++;
 }

 return 1;
}

Now i feel i need a new task but can't think of anything suitable, so I wonderd if you guys and gals had any ideas?

Thanks
Dave

How about a program that finds 26% of a number?

Then consider this: why do you want to learn a language you have no use for?

Your next task should be to change your existing code to be more correct. For example, main should specify int as its return value, not float. Also, while (x = 10) is not what you want. Remember (or learn) the difference between assignment and equality. Finally, standard practice is to return 0 to signify success. Better code formatting would also be a good thing to practice with a working program.

I want be a games programmer when i'm older, i need somewhere to start right?, I can't jump straight in i need to work my way up. before i can start practicing that kind of stuff, i need to know basics and get used to everything.

I know what your saying, but i still don't think i have enough skillz to make a basic game..

Don't worry about making a game yet. Just learn good programming habits (see my previous post) and do some easy programs until you can do them well. I believe there are some problems you can work on from this site's main pages.

One common problem that would fit as an extension to your current code is to make a calculator program. Start simply, with addition only, and expand it one step at a time.

hehe that was actually an idea i had , but wasn't sure, i'll try it, should be harder than the percentage one.

just to add, i made it float becuase it returns results with decimal
points.

Why not make a very simple text based game? That way you can learn to use classes, which is extremely important.

You're actually wrong there. The function main() itself does not return results in decimal points... It returns a 1. You're perhaps thinking that what you output to the user (which might be a decimal point) is actually what main() returns, which as stated is not the case. Read a little bit about functions in C++ and you'll hopefully understand what I mean.
