Program Input and Output

Using Printf

• The printf function is available in Perl, and it works just like the C and C++ printf routines.
• printf is pretty simple, but has about a gazillion options. See any good C reference, or simply man printf on any self respecting unix system for full options and usage instructions.
• Example:
  

  # Sample of printf
  $b = 1;
  $a = "Hello Number";
  printf("%s %d\n", $a, $b);
