I am new to c language. Can any one explain me how fast the oops program will compile

What is the "oops" program?

I'm guessing you mean "Object Oriented", in which case there isn't a single such program, and how long it takes depends on your hardware, OS, compiler, and a bunch of other variables too numerous to mention.

Small programs (written by students in a few hours) can be compiled in less than a second on modern machines.

Large programs written by professionals over many months and years can take many hours to compile.
