I want to write a cross-platform utility in C, which will display the compiler that is being used and so on.
How do i come to know the compiler being used, like turboc, Microsoft or lattice?

The best way to do this, and the method I have used for many years is to simply find out what symbols each compiler's preprocessor defines by default, and then do something like this:

#ifdef AZTEC_C
   ...code
#else
#ifdef MANX_C
   ...code
#else
#ifdef TURBO_C
   ...code
#else
#ifdef WATCOM
   ...code
#else
   Woah, Glenn!  Which compiler is this?
   /* Obviously, the above line causes a compilation error */
#endif
#endif
#endif
#endif
