Convert n to characters in s. Section 3.6 and 4.10 of The C Programming Language.

About the project:

  • Two ways to convert n to s:
    • Non-recursively: convert n to s in the reversed order then reverse the string before printing.
    • Recursively: convert n to s by recursively calling printd.

What did I learn from this:

  • Splitting source file into multiple files.
  • Recursion in C.
  • putchar() to put one char to output stream in C.
  • Static internal automatic variables in C.
