Printf Project

Overview

This project is an implementation of the printf function in C programming language. The printf function is used to print formatted output to the standard output stream. The goal of this project is to create a custom version of printf with support for a subset of format specifiers and options.

Installation

To use the custom printf function, follow these steps:

Clone the repository to your local machine:

git clone https://github.com/nouhelion/printf.git
Navigate to the project directory:

cd Printf
Compile the source code:

gcc -o myprintf myprintf.c main.c
Run the executable:

./myprintf

Authorized functions and macros

write (man 2 write)
malloc (man 3 malloc)
free (man 3 free)
va_start (man 3 va_start)
va_end (man 3 va_end)
va_copy (man 3 va_copy)
va_arg (man 3 va_arg)

Usage

The custom printf function can be used just like the standard printf from the C library. Include the header file "main.h" in your C source files to use the function.

#include "main.h"

int main() {
 _print("Hello, World!\n");
 _print("Hello, %s! The value of x is %d and y is %f.\n", "User", 42, 3.14);
 return 0;
}

Supported Format Specifiers
The custom printf function currently supports the following format specifiers:

%s - String
%d - Integer
%c - Character
%f - Float (single-precision)

Examples

Here are some examples of how to use the custom printf function:

#include "main.h"

int main() {
    int num = 42;
    float pi = 3.14159;
    char initial = 'J';
    char name[] = "John Doe";

    _print("Integer: %d\n", num);
    _print("Float: %f\n", pi);
    _print("Character: %c\n", initial);
    _print("String: %s\n", name);

    return 0;
}

Output :

Integer: 42
Float: 3.141590
Character: J
String: John Doe
