In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code.
In other words, leaks mean that dynamically-allocated memory cannot be released back to the operating system because the program no longer contains pointers that can access it. You’ve lost control of that piece of memory regardless of size and can no longer access it or free it.
