Introduction

ft_printf is a custom implementation of the printf function in C, providing a versatile and extensible solution for formatted output. The goal is to offer a lightweight and efficient alternative to the standard library's printf function.

Features

• Supports a wide range of format specifiers.
• Customizable and extensible.
• Lightweight and efficient.
• Easy to integrate into existing projects.

Usage

To use ft_printf in your project, include the ft_printf.h header file, and link your project with the compiled libftprintf.a library.

#include "ft_printf.h"

int main() {
    ft_printf("Hello, %s!\n", "world");
    return 0;
}

Format Specifiers

ft_printf supports the following format specifiers:

%c: Character %s: String %d, %i: Signed decimal integer %u: Unsigned decimal integer %x: Unsigned hexadecimal integer (lowercase) %X: Unsigned hexadecimal integer (uppercase) %p: Pointer (address)

Examples

#include "ft_printf.h"

int main() {
    char ch = 'A';
    int num = 42;
    double pi = 3.14159;

    ft_printf("Character: %c\n", ch);
    ft_printf("Integer: %d\n", num);
    ft_printf("Floating-point: %f\n", pi);

    return 0;
}
