📚 About the project

This project aims to recreate the behavior of printf, including it's basic error handling and some of it's flags. We mainly learning about variadic arguments.

Score

⚠️ Mandatory

• Your function has to handle the following conversions: <cspdiuxX%>
• Flags <-O.*> and minimum field width with all conversions

Functions in <ft_print_hex.c>

• <%x> || <%X>: ft_print_hex - prints a number in hexadecimal format in lowercase and uppercase

Functions in <ft_print_pointer.c> (and auxiliary functions)

• <%p>: ft_print_pointer - prints a pointer in hexadecimal format

Functions in <ft_print_unsig.c> (and auxiliary functions)

• <%u>: ft_print_unsig - prints an unsigned

Functions in <ft_printf.c>

• ft_printf - initialization function: start/end variable argument functions where argument numbers are undefined
• ft_format - checks each format specifier and calls as functions according to the collected format specifiers.

Functions in <ft_putchar.c>

• <%c>: ft_putchar - writes a specified character to the output unit provided

Functions in <ft_putnbr.c> (and auxiliary functions)

• <%i> || <%d>: ft_putnbr - prints the characters representing the numbers

Functions in <ft_putstr.c>

• <%s>: ft_putstr - writes the string to the given output unit

Makefile

• ft_printf.h
• Makefile

💻 Compiling the project

The library is written in C language and thus needs the -cc compiler and some standard C libraries to run.

Instruction

1. Compiling the project

     $ make
     $ make fclean
   

   

2. Execute your program

     $ cc ft_printf.c ft_putchar.c ft_putstr.c ft_print_unsig.c ft_print_pointer.c ft_print_hex.c ft_putnbr.c && ./a.out
