Difference between dangling pointer and memory leak

Question

I don\'t understand the difference between a dangling pointer and a memory leak. How are these two terms related?

Answer 1

A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer. There are three different ways where Pointer acts as dangling pointer.

1. De-allocation of memory
2. Function Call
3. Variable goes out of scope
