What are common dynamic allocation errors in C++?

Common dynamic allocation errors in C++ include memory leaks, double deletions, and accessing uninitialized pointers.

How can I prevent memory leaks in my C++ program?

To prevent memory leaks, always ensure that every new has a corresponding delete, and consider using smart pointers.

What are smart pointers?

Smart pointers are objects that manage the lifetime of dynamically allocated memory, automatically deallocating it when no longer needed.

Can you give an example of using smart pointers?

Sure! Here's a simple example using std::unique_ptr: std::unique_ptr<int> ptr(new int(10)); This automatically deletes the integer when ptr goes out of scope.
