_printf function

Description

This is a simple implementation of a function that works like C's printf function for the required cases.

---

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, handling the following conversion specifiers:

• c Prints the corresponding ASCII character
• s Prints character string (ending in '\ 0')
• % Prints % symbol, (e.g. %% prints one % symbol)

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

• Handle the following conversion specifiers:

• d Prints decimal (integer) number (base 10)
• i Prints integer (base 10)

2. Just because it's in print doesn't mean it's the gospel

• Create a man page for your function.

---

Additional Options:

• 'b' Prints the binary conversion of a integer
• 'u' Prints unsigned decimal (integer) number
• 'o' Prints octal number (base 8)
• 'x' Prints number in hexadecimal (base 16) lowercase
• 'X' Prints number in hexadecimal (base 16) uppercase
• 'r' Prints the reversed string
• 'R' Prints the rot13'ed string

EXAMPLE

• To print "Hello Holberton" use:

              #include "holberton.h"
  
              _printf("%s", "Hello Holberton");
  

• To print a line as "My age is, 23" use:

              #include "holberton.h"
  
              _printf("%s, %d", "My age is", 23);
  

---

RETURN VALUE

Upon successful return, this function return the number of characters printed (excluding the null byte used to end output to strings).

---

Man file:

• man_3_printf (Open it in linux using man command (e.g. man ./man_3_printf)

CHALLENGES FACED AND FUTURE FEATURES

This was a very interesting project where I managed to consolidate a lot of knowledge; it was quite challenging since we had 5 days to carry out the entire project and we had to understand in detail several characteristics of the PRINT-F function to achieve a similar implementation in our function. Additionally, we had to implement a local buffer of 1024 chars in order to call our write function as little as possible, designing this function took us a long time but it was quite useful to speed up the development of other functionalities within the project.

As a future features will be interesting to handle some additional custom conversion specifiers.
