_printf

A custom implementation of the printf function in C.

Description

This project aims to create a custom version of the printf function in C. The _printf function will handle various format specifiers like %c for characters, %s for strings, %d for integers, and %% for the % character...

Getting Started

Prerequisites

• C compiler (e.g., GNU GCC, CLang, etc.)

Compilation

To compile the project, use this command: gcc -Wall -Wextra -Werror -pedantic -std=gnu89 -Wno-format *.c

Usage

Include the header file "main.h" in your C code and call the _printf function with the desired format and arguments:

#include <stdio.h>
#include <limits.h>
#include "main.h"

/**
 * main - Entry point test function
 *
 * Return: Success
 */
int main(void)
{
	int len, len4, len6;

	len = _printf("test\n");

	len6 = _printf("%s\n", NULL);

	len4 = _printf("%s\n");
	printf("%s\n");

	_printf("char:%c, string:%s\n", 't', "test");

	_printf("somthin fake%\n");
	_printf("fake %vinci %\n");
	printf("real %vinci %\n");
	printf("somethn real%\n");

	printf("%d\n", len4);
	printf("%d\n", len);
	printf("%d\n", len6);
	_printf("char : %c\n", 'c');
	_printf("Percent:[%%]\n");
	_printf("Len:[%r]\n", 3);
	printf("Len:[%r]\n", 4);

	_printf("______________END_____________\n");
	return (0);
}

Format Specifiers

The custom _printf function supports the following format specifiers:

• %c: Print a single character.
• %s: Print a string of characters.
• %d: Print an integer decimal base 10.
• %i: Print and integer decimal.
• %%: Print a single '%' character.
• %x: Print in lowercase hexadecimal character.
• %X: Print in uppercase hexadecimal character.
• %b: Print in binary.
• %o: Print in octal.
• %p: Print a pointer in hexadecimal.
