You want to print leading zeroes if I understand it correctly.

So if a number is smaller than e.g 1,000,000 print a zero first
Next if it's smaller than 100,000, print another zero
Etc
Next print the number.

And there is sprintf / snprintf; e.g.

  1. sprintf(3): formatted output conversion - Linux man page
  2. C library function - sprintf() ,

snprintf is preferred as it protects agains buffer overflow.
