ft_printf is a custom implementation of the standard C printf function. The goal is to replicate the basic functionality of printf by parsing format strings and outputting formatted data to the standard output.

This project covers common conversion specifiers and flags, excluding the bonus features like wide characters or additional conversions.

• 🔍 How to parse complex format strings character by character.
• 🧩 Handling variable arguments using stdarg.h (va_start, va_arg, va_end).
• 🛠 Implementing conversion specifiers like:
  • %c (character)
  • %s (string)
  • %d and %i (signed decimal integers)
  • %u (unsigned integers)
  • %x and %X (hexadecimal integers)
  • %p (pointer addresses)
• 📏 Managing flags such as width, precision, zero-padding, and left justification.
• 📚 Working with number-to-string conversions.
• 🧹 Writing modular and maintainable code with multiple helper functions.
• ⚠️ Handling edge cases and invalid inputs gracefully.

• Variadic functions and stdarg.h
• String manipulation and buffer management
• Integer to string conversions (including base conversions for hex)
• Format parsing and flag interpretation
• Output formatting with padding and alignment
• Memory management and avoiding buffer overflows
• Writing clean, readable C code following 42 Norm

• Supports the standard printf format specifiers (without bonus extensions).
• Prints formatted output to the standard output.
• Handles multiple flags and modifiers in format strings.
• Returns the total number of characters printed.

• Correctly parsing and applying width and precision flags.
• Managing variable argument lists safely and efficiently.
• Implementing hexadecimal and pointer formatting.
• Handling edge cases like NULL strings and zero values.
• Ensuring output length matches standard printf.

This project deepened my understanding of:

• Low-level string and format parsing.
• Variadic functions in C.
• Writing flexible and robust formatting functions.
• Importance of meticulous testing and edge case handling.
