Heap Memory Allocation and Memory Leaks

Play an AI-generated podcast conversation about this lesson

Heap memory allocation has to be synchronized with its actual ______ in any program to be reused as much as possible.

usage

If the only pointer to a heap memory allocation goes out of or has its value overwritten before it is deallocated explicitly, then that memory cannot be recovered for later reuse and is essentially lost to the program, a phenomenon known as a memory .

scope

Conversely, it is possible for memory to be ______, but is referenced subsequently, leading to unpredictable results.

freed

Typically, the failure symptoms appear in a portion of the program unrelated to the code that causes the error, making it difficult to ______ the failure.

Why is it difficult to diagnose failure when the failure symptoms appear in a portion of the program unrelated to the code that causes the error?
