Mandatory 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. The format string is composed of zero or more directives. You need to handle the following conversion specifiers: * c * s * %

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

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

• Handle the following custom conversion specifiers: * 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
  

4. ** Nothing in fine print is ever good news: **

• Use a local buffer of 1024 chars in order 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 this way: \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.

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 printf :

• 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 what ever, 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
  

• All the above options work well together.
