How to Execute

Clone this repository in your local computer and cd into it:

$> git clone https://github.com/educastrob/ft_printf.git && cd ft_printf

In your local repository, run make

$> make 

make suports 4 flags:

  • make all or simply make compiles printf in its mandatory format
  • make clean deletes the .o files generated during compilation
  • make fclean deletes the .o and the libftprintf.a library file generated
  • make re executes fclean and all in sequence, recompiling the library

To use the ft_printf in your code you will need to include the header:

#include "ft_printf.h" 

When compiling your own code with libftprintf, don't forget to use the flags:

$> ... -lftprintf -L path/to/libftprintf.a -I path/to/ftprintf.h
