Team Project: Printf - Custom Formatting Function

Introduction

Welcome to our team project, Printf, where we will be creating a custom formatting function for producing output according to a specified format. This project aims to simulate the behavior of the standard C library's printf function while also handling some custom conversion specifiers. We are dedicated to delivering a reliable and efficient solution for printing formatted output in C.

Motto

"I'm not going anywhere. You can print that wherever you want to. I'm here and I'm a Spur for life." - Team Printf

Conversion Specifiers

Our custom printf function will be able to handle the following conversion specifiers:

• %d: Print signed decimal integer
• %i: Print signed decimal integer
• %u: Print unsigned decimal integer
• %o: Print unsigned octal (base 8) number
• %x: Print unsigned hexadecimal (base 16) number (lowercase)
• %X: Print unsigned hexadecimal (base 16) number (uppercase)
• %p: Print pointer address

Custom Conversion Specifiers

In addition to the standard conversion specifiers, our custom printf function will also handle the following custom conversion specifiers:

• %r: Print a string in reverse
• %R: Print the Rot13 encoding of a string
• %w: Print the string with alternating uppercase and lowercase characters
• %s: Print the string, replacing spaces with underscores
• %S: Print the string, replacing spaces with asterisks

Local Buffer Optimization

To minimize the number of calls to the system's write function, we will utilize a local buffer of 1024 characters in our implementation.

Additional Features

Our custom printf function will support the following features:

• Field Width: Allowing the user to specify the minimum width for the output.
• Precision: Providing the ability to set the precision for floating-point numbers.
• Flag Characters: Handling flag characters like 0 and - for alignment purposes.

Collaboration

We believe that education and experience go hand in hand. As a team, we are committed to working together, sharing knowledge, and supporting each other to create a powerful and efficient custom printf function.

Let's Print!

With the combined effort of our team, we are confident that our custom printf function will be a success and serve as a valuable tool for handling formatted output in C. Let's embark on this journey together and make printing in C a smoother and more enjoyable experience.
