What are raw pointers in C++11 and how should I use them?

Raw pointers in C++11 are variables that hold memory addresses. They allow direct memory access but require careful management to avoid memory leaks.

Can you give me an example of how to declare and use a raw pointer?

Sure! You can declare a raw pointer like this: int* ptr; Then, you can allocate memory using ptr = new int; and access it with *ptr = 10;.

What are the risks of using raw pointers?

The main risks include memory leaks, dangling pointers, and undefined behavior if you access memory that has been freed.

How do raw pointers compare to smart pointers?

Smart pointers, like std::unique_ptr and std::shared_ptr, automatically manage memory and help prevent leaks and dangling pointers, making them safer alternatives.
