_printf Function

Description

The _printf function produces output according to a given format. It is a custom implementation of the printf function in C. This function accepts a format string containing zero or more directives and writes output to the standard output stream (stdout). The format string may contain conversion specifiers such as %c, %s, and %%, which are replaced by the corresponding arguments passed to the function.

Prototype

int _printf(const char *format, ...);

Return Value

The function returns the number of characters printed, excluding the null byte used to end output to strings.

Conversion Specifiers

The _printf function handles the following conversion specifiers:

• %c: Print a single character.
• %s: Print a string.
• %%: Print a literal % character.
• %d and %i: Print signed decimal integers.

The function does not handle flag characters, field width, precision, or length modifiers.

Compilation Your code will be compiled this way:

1. Compile Command: Use the given compilation command:

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

2. Header Inclusion: Ensure that your main files include the main header file main.h:

   #include "main.h"

3. Avoid Main Functions in Root Directory: Do not include any main functions in the root directory of your project. If you need to include main functions for testing purposes, place them in a separate folder, such as a test folder, and ensure they are not included in the compilation command provided.

Following these guidelines will help ensure that your code compiles successfully and meets the project's requirements.
