42 ft_printf project - to recode the printf function from libc

ft_printf

The aim of this project is to recode the printf function from the C Library.

In this project, you can learn how to use variadic arguments. More importantly, you can challenge yourself to structure the code well, so it can be extended to different usecases.

Technical considerations

• Allowed functions: malloc, free, write, va_start, va_arg, va_copy, va_copy
• All heap allocated memory space must be properly freed when necessary
• It will manage the following conversions: cspdiuxX%
• It will manage any combination of -0.* flags and minimum field width with all conversions

How to test

Run the following commands. You can replace the test.c with your own test file

$ git clone https://github.com/qingqingqingli/ft_printf
$ cd ft_printf
$ make
$ gcc test.c libftprintf.a
$ ./a.out

Examples

• Create libftprint.a and compile with test.c

• Run a.out to view the test results (with some examples)
