Almost every one of you must have written a program, compiled it and  then ran it to see the fruits of your hard labour. It feels good to  finally see your program working, isn’t it? But to make all of this  work, we have someone else to thankful too. And that is your compiler  (of course, assuming that you are working in a compiled language, not an  interpreted one) which also does so much hard work behind the scenes.

In this article, I will try to show you how the source code that you  write is transformed into something that your machine is actually able  to run. I am choosing Linux as my host machine and C as the programming  language here, but the concepts here are general enough to apply to many  compiled languages out there.
