  • How is printf implemented?

    Vararg: Variable argument functions. Printf and scanf are two functions that you will encounter to use any number of arguments.

  • Printf working principle. Printf takes multiple arguments using vararg function.
  • Scanf working principle. It iterates each characters of user provided string and stops at “%”.
