What is programming? What can be done with it? I do not feel the need to say anything about this. If you do not know the answers to the questions, then know the answers first, then read the rest.

   Those who have computers for practice, codeblocks-16.01mingw-setup.exe and those who do not have access to the online compiler ideone or c4droid app.
   Tutorial is open if there is any question ...
   I'm finished today's episode by writing a little bit code for the beginners
   int main ()
   {
   printf ("Welcome!
   \ nHope you will enjoy the tunes \ n ");
   // printing an welcome message ...
   return 0;
   }
