ft_printf is a project at 42 School that requires implementing a simplified version of the C standard library function printf. The goal of this project is to understand how printf works under the hood, including formatting specifiers, variable argument lists, and memory management.
The ft_printf function should behave similarly to printf, and support a subset of the most common formatting options. The focus of this project is on learning how to handle variadic arguments and formatting types in C.
ft_printf supports the following key format specifiers:
%c: Prints a character.%s: Prints a string.%p: Prints a pointer address in hexadecimal format.%d: Prints a signed decimal integer.%i: Prints a signed integer (same as%d).%u: Prints an unsigned decimal integer.%x: Prints an unsigned hexadecimal integer (lowercase).%X: Prints an unsigned hexadecimal integer (uppercase).%%: Prints a literal%character.
To compile and test ft_printf, follow these steps:
- Clone the repository:
git clone git@github.com:AnnLvu/printf_42.git cd printf_42
make # Compiles the ft_pritf library ⚒️
make clean # Cleans up object files 🧹
make fclean # Full cleanup of generated files 🧼
make re # Rebuild everything from scratch 🔄
