Implementation of the printf() function in C.

Primary LanguageC

0x11. C - printf team project

This group project focuses on implementing a custom version of the printf function in C, handling various conversion specifiers and custom functionalities. Below are the tasks for this project:

Tasks

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

Write a function that produces output according to a format.

  • Prototype: int _printf(const char *format, ...);
  • Returns: the number of characters printed (excluding the null byte used to end output to strings).
  • Write output to stdout, the standard output stream.
  • Format is a character string composed of zero or more directives. See man 3 printf for more detail.
  • Handle the following conversion specifiers: c, s, %.
  • You don’t have to reproduce the buffer handling of the C library printf function.
  • You don’t have to handle the flag characters, field width, precision, or length modifiers.

1. Education is when you read the fine print. Experience is what you get if you don't

Handle the following conversion specifiers: d, i.

  • You don’t have to handle the flag characters, field width, precision, or length modifiers.

2. With a face like mine, I do better in print

Handle the following custom conversion specifier:

  • b: the unsigned int argument is converted to binary.

3. What one has not experienced, one will never understand in print

Handle the following conversion specifiers: u, o, x, X.

  • You don’t have to handle the flag characters, field width, precision, or length modifiers.

4. Nothing in fine print is ever good news

Use a local buffer of 1024 chars to call write as little as possible.

5. My weakness is wearing too much leopard print

Handle the following custom conversion specifier:

  • S: prints the string.
    • Non-printable characters (0 < ASCII value < 32 or >= 127) are printed as \x followed by the ASCII code value in hexadecimal (upper case - always 2 characters).

6. How is the world ruled and led to war? Diplomats lie to journalists and believe these lies when they see them in print

Handle the following conversion specifier: p.

  • You don’t have to handle the flag characters, field width, precision, or length modifiers.

7. The big print gives and the small print takes away

Handle the following flag characters for non-custom conversion specifiers:

  • +
  • space
  • #

8. Sarcasm is lost in print

Handle the following length modifiers for non-custom conversion specifiers:

  • l
  • h
  • Conversion specifiers to handle: d, i, u, o, x, X.

9. Print some money and give it to us for the rain forests

Handle the field width for non-custom conversion specifiers.

10. The negative is the equivalent of the composer's score, and the print the performance

Handle the precision for non-custom conversion specifiers.

11. It's depressing when you're still around and your albums are out of print

Handle the 0 flag character for non-custom conversion specifiers.

12. Every time that I wanted to give up, if I saw an interesting textile, print whatever, suddenly I would see a collection

Handle the - flag character for non-custom conversion specifiers.

13. Print is the sharpest and the strongest weapon of our party

Handle the following custom conversion specifier:

  • r: prints the reversed string.

14. The flood of print has turned reading into a process of gulping rather than savoring

Handle the following custom conversion specifier:

  • R: prints the rot13'ed string.

15. *

All the above options work well together.
