printf functions
The _printf function is a custom implementation of the C programming function printf. It returns the number of characters printed and writes the output to stdout. It includes the conversion specifiers : c, s, %, d, x, X, u, o, rot13 and i.
#include "holberton.h"
_printf("The %s jumped %d times! -%c", "dog", 7, 'C');
output : The dog jumped 7 times! -C
