Скачать или смотреть Nullptr, Resolving Dangling Pointers (Part 6)

Hello devs, working with pointers can be a little tricky because we have to deal with memory management. If we are pointing to a memory address and then the variable that it refers to gets deallocated (such as a stack variable going out of scope), then our pointer is known as a dangling pointer. It is essentially pointing to something that no longer exists. Dereferencing this pointer will result in UB (undefined behavior) and can significantly ruin the program. Today we will resolve a dangling pointer by setting its value to nullptr which is essentially the memory address (0). We use this as a flag to indicate that the pointer is not pointing to valid memory and should not be dereferenced.

This is part 6 of working with memory addresses and pointers. I strongly recommend watching the next parts to learn more about pointers in C++
