4.3 Standard I/O Function Interface Printf
Use "%%" to specify a "%" character as an output character rather than as a control specifier.
The printf function outputs characters using putchar.
The printf function uses approximately 80 bytes of stack as a work area (excluding the
arguments and stack used by putchar).
