It's a recoding of the printf function in C. Printf can write combinations of strings, numbers of different bases, even pointers, to the stdout, with various options.

• first run make to create the libftprintf.a binary.
• then #include ft_printf.h in your .c files where you use these libft functions.
• compile your files with the library with following flags:

gcc -L. -lftprintf your_file(s).c

The function is called with the standard printf usage options.

You can print strings with %s, or characters with %c. For decimal numbers, use %d or %i, or %u for unsigned. If you want another base, use %o for octal, %x for hexadecimal and %X for CAPS hexadecimal. Finally, %p displays a pointer address.

It can manage any combination of the following flags: - and 0 (%-5s or %05s), as well as the width and precision like: (%5s), (%.5s)

ft_print("The number of %s is %d.", "people", 5);
// The number of people is 5.

ft_printf("%d is %x in hex and %o in octal.", 30, 30, 30);
// 30 is 1e in hex and 36 in octal.
