42-cpp06

The seventh C++ module of the 42 curriculum, focused on C++ casts.

This project covers the four explicit cast operators of C++ and the scenarios where each is appropriate: type conversion, serialization, and runtime type identification.

Usage

Each exercise (ex00 to ex02) contains its own Makefile. Compile and run individually:

cd ex00
make
./ex00

Exercises

• ex00: ScalarConverter — converts a string literal to char, int, float, and double using static_cast, handling special values (nan, inf, non-displayable characters).
• ex01: Serializer — converts a pointer to uintptr_t and back using reinterpret_cast, demonstrating pointer serialization without data loss.
• ex02: Type identification — given a randomly instantiated A, B, or C object through a Base*, identify the real type using dynamic_cast on both pointers and references.

Code Structure

Each exercise is self-contained in its own directory with its own source files, headers, and Makefile, following the standard 42 module layout.
