Why use new and delete at all?

Question

I am new to C ++ and I wonder why should I even use new and delete? This can cause problems (memory leaks), and I don’t understand why I should not just initialize the variable without a new statement. Can someone explain this to me? It is difficult to resolve this specific issue.

Answer 1

For the purposes of history and efficiency, C ++ (and C) memory management is explicit and manual.

Sometimes you can allocate a call stack (for example, using VLA or alloca (3) ). However, this is not always possible because
