I want to know which is the best 'C' compiler for Windows 7?

I'm using dev c++ but it has creating some problems while working with windows 7

So want the best compiler which is works with windows 7.

By best I mean whiich will give me the best performance.

well, there are many to choose from:

• Visual Studio, works 'best' with MS OSes
• Eclipse or Code::Blocks with GCC, works 'best' with standard C99 code
• Pelles C works best at being simple

Your choice really boils down to what you require and what your working with, so just look at the above examples, pick what suites you best
