_printf

This _printf project is about building a function as similar as possible to the original printf.

Features

• The main function uses structures to call the function corresponding to the case.
• The function has a buffer that stores and prints the output strings every 1024 bytes just like the original printf.
• The returns of our function are the number of characters printed, and when there's an incorrect input the return is going to be -1 as an error, just like the original printf.

Session log:

12/02/21

Session 0 (12/03/21 - Duration: 3:35, from 18:34 to 22:09)

• Planned modules for printf (Miro).
• First draft of flowchart.
• Proof of concept for task 1 (basic printf with `%c`, `%s` and `%%`).

Tomorrow

• Function pointers for proof of concept.
• Structure for printf's modules.

13/03/21

Session 1 (Duration: 3:08, from 10:52 to 14:00)

• Function pointers implementation of proof of concept for task 1.

Next session:

• Edge cases for printf's function pointer implementation.
• Implementation of %d and %i.
• Buffer allocation.

Session 2 (Duration: 4:56, from 17:36 to 22:32)

• Edge cases for printf's function pointer implementation.
• Implementation of %d and %i.

Next session:

• Buffer allocation.

Session 3 (Duration: 4:56, from 23:18 to +1 01:03)

• Buffer allocation.

Tomorrow:

• Planning for split work, implementation of other formats.

Session 4 (Duration: 03:10, from 16:14 to 19:25)

Session 5 (Duration: 02:54 , from 20:33 to 23:27)
