Repository Name

This repository contains a custom implementation of the printf function with support for various conversion specifiers. Below is a list of tasks and features included in this project.

Breakdown

Basic Tasks:

Create a custom printf function that supports basic conversions, such as printing characters, strings, and percent signs.

Extend the printf function to handle 'd' and 'i' conversions (decimal and integer).

Advanced Tasks:

Implement a custom conversion specifier '%b' to print unsigned integers in binary format.

Extend the printf function to handle 'u', 'o', 'x', and 'X' conversions (unsigned, octal, hexadecimal lower-case, and hexadecimal upper-case).

Optimize the function using a local buffer of 1024 characters to reduce the number of write calls.

Implement a custom conversion specifier '%S' to print strings with non-printable characters represented as '\x' followed by their ASCII code in hexadecimal.

Handle the 'p' conversion specifier (print memory address).

Implement support for flag characters '+', 'space', and '#' for non-custom conversion specifiers.

Handle length modifiers 'l' and 'h' for non-custom conversion specifiers 'd', 'i', 'u', 'o', 'x', and 'X'.

Implement support for the field width for non-custom conversion specifiers.

Implement support for the precision for non-custom conversion specifiers.

Handle the flag character '0' for non-custom conversion specifiers (padding with zeros).

Handle the flag character '-' for non-custom conversion specifiers (left-justify).

Implement a custom conversion specifier '%r' to print the reversed string.

Implement a custom conversion specifier '%R' to print the rot13'ed string.

Ensure that all the above options work well together.

Tasks

Custom printf function for basic conversions
- Create a function int _printf(const char *format, ...) that mimics the behavior of the standard printf function.
- The function should support the following conversion specifiers:
  - %c: Print a character.
  - %s: Print a string.
  - %%: Print a percent sign.
- The function should return the number of characters printed (excluding the null byte).

Support for 'd' and 'i' conversions
- Extend the _printf function to handle the 'd' and 'i' conversion specifiers.
Repo: printf
Handle custom conversion specifier 'b'
- Implement a custom conversion specifier '%b' to print an unsigned integer in binary format.
- Example:
_printf("%b\n", 98);

output >> 1100010

Repo: printf
Support for 'u', 'o', 'x', and 'X' conversions
- Extend the _printf function to handle the 'u', 'o', 'x', and 'X' conversion specifiers.

Optimize with a local buffer
- Use a local buffer of 1024 characters to minimize the number of calls to the write function.
Repo: printf
Handle custom conversion specifier 'S'
- Implement a custom conversion specifier '%S' to print strings with non-printable characters represented as '\x' followed by their ASCII code in hexadecimal.
- Example:
_printf("%S\n", "Best\nSchool");

output >> Best\x0ASchool

Repo: printf
Handle conversion specifier 'p'
- Extend the _printf function to handle the 'p' conversion specifier.
Repo: printf
Handle flag characters '+', 'space', and '#'
- Implement support for the flag characters '+', 'space', and '#' for non-custom conversion specifiers.
Repo: printf
Handle length modifiers 'l' and 'h'
- Implement support for the length modifiers 'l' and 'h' for non-custom conversion specifiers 'd', 'i', 'u', 'o', 'x', and 'X'.
Repo: printf
Handle field width
- Implement support for the field width for non-custom conversion specifiers.
Repo: printf
Handle precision
