i tried to run this program but it comes up with the windows 6th grade algebra quiz has encuontered a problem and has to close message can
anyone help?

It shouldn't compile because C++ does not allow recursive calls to main.

what doyou mean?

I mean it shouldn't compile.

it says that there arent any errors onvisual studio 2003 .net

Then consider using another compiler.;) If you want to start over when something in the user's choice goes wrong you can either provide an ethernal loop around the code that should be performed over and over again until the user gives a correct input or use labels. I recommend you the first option. If you choose the second one you would probably want to know something about "goto"...

I saw somewhere that C++98 states,

3.6.1, par 3
[...]
The function main shall not be used (3.2) within a program.

>it says that there arent any errors onvisual studio 2003 .net
That's nice, and your point is? I get the same lack of error, but that doesn't make it any less wrong. The only difference between you and me is that I know it's wrong and you're trying to give the "it works for me" argument that so many ignorant people love.

>you would probably want to know something about "goto"...
Yes, and that something would be that it should be used sparingly. I just felt the need to chime in before somebody says "NEVER use goto, it's teh EVIL!!!!111"

ok you keep workin on that...

whatever ok does anyone know where to get a new free (hopefully i dont exactly have 300\$ siting on my desk ('.')) good compiler?

thx i got it
