Hi... I know there are better boards for this but I was hoping someone out there would immediately recognize the fix for this. I'm a student and the assignment is due Wednesday so the sooner the better =) In C++, I have: int score; char str; itoa(score, str, 10); I'm trying to convert my integer "score" into a string - I figured itoa was the best way. It worked fine in Visual C++ but now that I'm compiling at school on a Unix machine, it gives me the error: implicit declaration of function 'int atoi(...)' How do I use atoi "explicitly"??? Thanks!
