10 Questions
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.
diagnose
Such issues are ______ in languages with automatic garbage collection.
ameliorated
If a pointer to a heap memory allocation goes out of scope or has its value overwritten before it is deallocated explicitly, what happens to that memory and what is this phenomenon called?
The memory cannot be recovered for later reuse and is essentially lost to the program, this is known as a memory leak.
What can happen if memory is freed but is referenced subsequently?
This can lead to unpredictable results.
Why is it important to synchronize heap memory allocation with its actual usage in a program?
To maximize reuse of memory and avoid memory leaks.
How are issues related to memory leaks and freed but referenced memory ameliorated in some programming languages?
They are ameliorated in languages with automatic garbage collection.
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?
Because the symptoms are not directly related to the root cause, making it challenging to identify the source of the failure.
