: You must parse a file to draw empty or filled rectangles based on coordinates, width, height, and a character for the border/fill.

In this exam, you must write a function called get_next_line that, when called repeatedly, reads from a file descriptor and returns one line at a time. The typical prototype is char *get_next_line(int fd) . This is more than a file-reading exercise; it's a lesson in memory management and state preservation. You are allowed to use read , free , and malloc for this task. The core technique you must master is the use of to preserve state between multiple function calls. Getting this right is the key to a clean and functional get_next_line . 42 Exam Rank 03

If your exam draws the ft_printf challenge, you must reproduce specific formatting behaviors. The exam version is stripped down compared to the full curriculum project, focusing strictly on core conversions. Requirements Your function must be prototyped as follows: int ft_printf(const char *format, ...); Use code with caution. It must handle the following three specifiers perfectly: %s : Prints a string of characters. %d : Prints a signed base-10 integer. %x : Prints a lowercase hexadecimal number.

A classic pitfall in loops and mathematical checks. Ensure your inequalities ( < vs <= ) precisely match the subject requirements, especially when calculating whether a pixel lies on the boundary of a shape.

You must know exactly when to use malloc and ensure every allocated block is freed under every possible exit condition.
