What is RAII in C++?

Can you explain what RAII is in C++?

RAII stands for Resource Acquisition Is Initialization. It's a programming idiom used in C++ to manage resource allocation and deallocation.

How does RAII help with memory management?

RAII helps by tying resource management to object lifetime. When an object is created, it acquires resources, and when it goes out of scope, the resources are automatically released.

Can you give an example of RAII in action?

Sure! A common example is using smart pointers like std::unique_ptr. When a std::unique_ptr goes out of scope, it automatically deletes the associated memory.

What are the benefits of using RAII?

The benefits include automatic resource management, reduced memory leaks, and clearer code that is easier to maintain.
