The goal of this 42 school project is to recreate the C standard library function printf() as a library named "libftprintf.a". We needed to discover and use variadic function. Variadic functions are function that can take a variable number of arguments. A minimum of one is required for ft_printf() and an additionnal one for each conversion. After, this project is done, it can be added to libft to have a more complete library.
The conversions that were required are the following:
- %c, prints a char
- %s, prints a char* (string)
- %p, prints that address of a void*
- %d, prints a decimal in base 10
- %i, prints an integer in base 10
- %u, prints an unsigned decimal in base 10
- %x, prints a number in hexadecimal lowercase format
- %X, prints a number in hexadecimal uppercase format
- %%, prints a percent sign
To use this library, you have to:
- Clone this repository into your project
- Go to the root of the repository and use
make - Include
"ft_printf.h"in your project - Link the library at compile time by adding
-L/ft_printf_42 -lftprintfto your compilation line
