The Task: Re-implement the printf function. However, unlike your project, the exam restricts the conversions. You typically only need to handle:

The Strategy:

If you don't get ft_printf, you will likely get get_next_line. This function reads a line from a file descriptor.

The Prototype:

char *get_next_line(int fd);

Key Concepts:

Logic Structure:

  • Extract Line:
  • Update Remainder:

    • Common Pitfalls:

  • Typing Speed: You have 3 hours, but retyping va_list logic or read loops from memory takes time. Practice typing the skeleton code until it is muscle memory.
