Printf Project

Description

This project is a simulation of the printf function in C with its most important features, it was made in the software development program of Holberton School.

Man page

The man page is a file wich explains in detail how the function works. If you want see a full explanation of this function you can run our man page this way:

$ man ./man_3_printf

Flowchart

Usage

Syntaxis

To call the _printf() function the next code is required:

#include "main.h"

int main() 
{
    _printf("string to print");
    return (0);
}

Compilation

To compile the program this command has to be executed:

$ make -f makefile

This will create a compilation file, its name is main.out. You can run this file in your terminal with the next command:

$ ./main.out

Parameters

The next chart explains the detailed functionality of the parameters that the function accepts, respectively with each data type.

Indicator	Data type	Description
%d	int	Print an int as a signed decimal number
%i	int	Print an int as a signed decimal number
%u	int	Print an unsigned as an unsigned decimal number
%o	int	Print an unsigned as an unsigned octal number
%x	int	Hexadecimal notation (using lowercase letters a-f)
%X	int	Hexadecimal notation (using uppercase letters A-F)
%c	int	Convert an int to an unsigned character and print the resulting character
%s	char *	Print a string pointed to by a char *
%p	void *	Print a void * argument in hexadecimal (ANSI C only)
%%	char	Print a single % character
%b	int	Print a converted number to binary (base 2)
%r	char *	Print a reversed string
%R	char *	Converts a string to rot13 and prints it

Here's an example of how does the parameters work in our _printf() function:

#include "main.h"

int main()
{
    _printf("Cohort: %i", 19);
    return (0);
}

The output of this main function will be:

$ ./main.out
Cohort: 19
