ft_printf is a project that requires you to recreate the functionality of the standard C library function, printf. In this project, you will write a function that takes a format string and a variable number of arguments and outputs the formatted string.
To use this function in your projects, you must first compile it into a static library file. To do this, run the following command:
make
This will compile the library into a file called libftprintf.a.
To use the function in your code, you must include the ft_printf.h header file:
#include "ft_printf.h"
You can then call the ft_printf function with a format string and a variable number of arguments:
int ft_printf(const char *format, ...);
The function returns the number of characters printed, excluding the null byte used to end the output to strings.
The function recognizes the following format specifiers:
- %c: Character
- %s: String
- %p: Pointer address
- %d or %i: Signed decimal integer
- %u: Unsigned decimal integer
- %x or %X: Hexadecimal integer
Conclusion The ft_printf project is an important project that will help you to gain a better understanding of how the printf function works and how to write your own C functions that take variable arguments. By completing this project, you will gain a deeper understanding of how to format output in C and how to work with variable arguments in your functions.
