ft_printf

Description

This project re-implements a small, mandatory subset of printf() as a static library libftprintf.a. The required conversions are:

• %c %s %p %d %i %u %x %X %%

Instructions

Build the library:

make

This produces libftprintf.a at the repository root.

Clean:

make clean

Full clean:

make fclean

Rebuild:

make re

Algorithm & architecture

1. ft_printf(format, ...) initializes a va_list and calls the parser.
2. The parser scans the format string left-to-right.
   • Normal chars are written immediately with write(1, ...).
   • When a % is found, the next char is treated as a specifier and dispatched.
3. Each conversion handler prints its representation and returns the number of characters written.

Resources

• man 3 printf
• man stdarg
