Any problem you run into you can ask about here on the forum and it will get answered - provided you do something about your horrible spelling. Most people here are not patient with people who can't be bothered to spell correctly (as in "why", "you"). This is likely to be your only warning.
can i use allegro with turbo C++ compiler
No, you can't.
EDIT: honestly, if you're in Windows, you're better off using a Windows compiler (ie, MinGW). If you don't like Dev-C++ but do like RHIDE (say), there's no particular reason you cannot use RHIDE and use it with MinGW rather than DJGPP.
My recommendation is to look through some other free IDEs/editors and see if you like any of those more than you do Dev-C++.
