Introduction

The ft_printf project tasks you with recreating the behavior of the standard C library function printf. This function allows for formatted output, where you can specify various format specifiers to control the display of data.

Installation

1. Clone the repository:

git clone https://github.com/Kelho0812/ft_printf.git
cd ft_printf

2. Build the project:

make

Usage

To use ft_printf, include the ft_printf.h header file in your project. Call the function with the desired format string and additional arguments.

Example:

#include "ft_printf.h"

int main(void)
{
    ft_printf("Hello, %s! The answer is %d.\n", "World", 42);
    return (0);
}

Format Specifiers

The following format specifiers are supported in ft_printf:

• %c: Character
• %s: String
• %p: Pointer
• %d or %i: Signed integer
• %u: Unsigned integer
• %x: Hexadecimal (lowercase)
• %X: Hexadecimal (uppercase)
• %%: Percent sign

Example

#include "ft_printf.h"

int main(void)
{
    int value = 42;
    char *str = "World";
    ft_printf("Hello, %s! The answer is %d.\n", str, value);
    return (0);
}

This will output:

Hello, World! The answer is 42.
