• %c - Single character
• %s - String
• %p - Pointer address
• %d - Decimal (base 10) integer
• %i - Integer in base 10
• %u - Unsigned decimal (base 10) integer
• %x - Hexadecimal (base 16) integer lowercase
• %X - Hexadecimal (base 16) integer uppercase
• %% - Percentage sign

📋 Usage

#include "ft_printf.h"

int main(void)
{
    ft_printf("Hello %s!\n", "world");
    ft_printf("Number: %d\n", 42);
    ft_printf("Hexadecimal: %x\n", 42);
    return (0);
}

⚠️ Function Prototype

int ft_printf(const char *format, ...);

Returns the number of characters printed (excluding the null byte used to end output to strings).
