The printf function allows its user to print a string of characters, a character or a number and many other things requested by the user on the terminal. Its syntax is generally printf("format", arg_1, arg_2, ..., arg_n);

format being the string of characters contained between the inverted commas ("") and arg_1, etc... being arguments for printing the string of characters.

In this project, we recreate the printf usually included in the standard <stdio.h> header with its requirements and constraints, using a number of different functions and tool functions to make it as complete as possible.

Here's a diagram showing how all the printf code reacts to a command being executed

• Allowed editors: vi, vim, emacs
• All your files will be compiled on Ubuntu 20.04 LTS using gcc
• All your files should end with a new line
• Your code should use the Betty style. It will be checked using betty-style.pl and betty-doc.pl
• No more than 5 functions per file
• The prototypes of all your functions should be included in your header file called main.h

• Make a FORK of this directory

• Make a git clone of this fork on your terminal

git clone (the link given with your github)

• To compile all the data you can use this:

gcc -Wall -Werror -Wextra -pedantic -std=gnu89 -Wno-format *.c

• Add your contributions (code or documents)

• Commit and push

• Wait for pull request to be merged

To test the program, you can use a main.c file containing different instructions. Include the given "main.h" in your header. In your instructions, start with a prototy of type

int main (void)

Then declare an int (in the examples below "len") which you initialise with the desired values.

len = _printf("Negative:[%d]\n", -762534);

Then use the printf command to display what you want:

_printf("%d\n", len);

And return (0) as it is an int

Examples:

#include "main.h"

int main (void)
{
    int len;

    len = _printf("Let's try to printf a simple sentence.\n");
    return (0);
}

Output : Let's try to printf a simple sentence.

or

#include "main.h"

int main (void)
{
    int len;
    
    len = _printf("Negative:[%d]\n", -762534);
    _printf("%d\n", len);
    return (0);
}

Output: -762534

You can use it to display your terminal according to the command you give it.
