Well, at school and when I telnet to my CS class, we use g++. I believe that is a compiler used only by Linux. Im not sure tho, cuz I am very new to Linux. I also use Dev C++ at my house, when I am not connected to the schools network. And neither one of those allowed this program to run.
By string declaration, do you mean string fname("aaa") or fname.equals("aaa"). I am wondering, cuz I have never seen either one before either. When, declareing a string, I always just wrote string fname = "aaa". And I have never seen fname.equals("aaa"). So, yeah, I am still a little confused as to how this is to work.
And about viewing the header file. Im not sure about that. I could always look, but the last time I had a question and lookedin teh header file for my answer. All the header file provided me was alot jumping around and confusing variable names. Maybe that was because it was the math.h file, but eh. Ill give it a look and see what I find.
