Faster Statement Execute
Which one will execute faster if(flag==0) or if (0==flag) and why?

It all depends on what assembly code the compiler generates. Essentially, do "0 == flag" and "flag == 0" compile down to the same code, or not?

Both gcc and Visual Studio generated the exact same machine code for both forms (as well as for !flag), so neither version would be faster than the other for platforms using those compilers. Frankly, I'd be surprised if any compiler generated different code for the two forms.
