ok i will try that out thanks

WOW Albatross your a god at this all my errors are finished but i got two warnings about int no1, po1;
Albatross (4553)
A god? Hmm... are birds gods? I dunno... do we have any philosophical programmers in this forum?!?

The warnings... what are they? I usually ignore warnings if I know exactly what I'm doing, but they're useful for telling me that I might not know what I'm doing. I expect it might be similar with you...

P.S.- Thanks.

Well i guess we can finish this off with that my main problems are solved in this math solver and to be nice i will provide the code for you guys if you want to use or alter anything and add whatever you want but please tell me what you are adding so i to can add the same to my code that way i know what others want in this code so heres my code:

{note to the admin(s)} is it allright if this forum doesn't get deleted (if they are unactive for a long time) that way i don't have to retype my code when i go to change it arround thanks.


also thanks to everyone that has helped in the success of this code and even though this is solved how do you input a divide command so the user can plug in there own numbers i have already tryed

{
int no2, no3;
cout << "1st #: \n";
cin >> no2;
cout << "2nd #: \n";
cin >> no3;
cout << "this = " no2/no3;
}


or something like that lol thanks again and happy coding

nevermind i fixed the code somehow but thanks to albatross for teaching me how to shorten up my code it was very useful also thanks to everyone else for helping me in making this code prefect (in my eyes) thanks again

Skillet

also i will post my final code tomorrow after i fix my spelling and make it look a little more nicer

night guys thanks again and happy coding

ohh albatross i got my errors fixed i forgot to delete the lines that had the code 
 
 
int no1, po1


after i deleated those this is now working nicely without any errors thanks so much buddy
P.S. Birds are gods
