What are some effective memory management strategies in C++?

In C++, effective memory management strategies include using smart pointers, manual memory management, and RAII (Resource Acquisition Is Initialization). Smart pointers like std::unique_ptr and std::shared_ptr help manage memory automatically.

Can you explain how smart pointers work?

Sure! Smart pointers are objects that manage the lifetime of dynamically allocated memory. For example, std::unique_ptr ensures that only one pointer can own the memory, automatically deleting it when the pointer goes out of scope.

What is RAII and how does it help with memory management?

RAII is a programming idiom where resources are tied to the lifetime of objects. When an object is created, it acquires resources, and when it is destroyed, it releases them. This helps prevent memory leaks and ensures proper resource management.

Are there any common pitfalls in memory management I should be aware of?

Yes, common pitfalls include memory leaks, dangling pointers, and double deletions. Always ensure that every new has a corresponding delete, and prefer smart pointers to avoid these issues.
