Does a garbage collector collect stack memory, heap memory, or both?

Question

I read lot of articles about garbage collection and almost all article tells about heap memory. so my question is \"garbage collection collects stack memory or heap memory or bo

Answer 1

Heap memory.

Garbage collection is a method of deallocating memory that isn't being used anymore. Sometimes the "isn't being used anymore" part is tricky. With the stack, as soon as a function returns, we can be confident (excepting programmer error) that the local variables aren't being used anymore, so they are deallocated automatically at that time in nearly every language/runtime.
