Tag: heap

The heap is a specialized region of a computer’s memory used for dynamic memory allocation. Unlike the stack, which automatically manages memory via LIFO scope rules, heap memory lifespan is controlled manually by the programmer or by a garbage collector. Variables allocated on the heap persist across function calls until explicitly deallocated. This makes the heap ideal for large data structures or objects with unpredictable lifetimes. In C and C++, developers use `malloc()` and `new` to allocate heap memory, requiring manual cleanup to prevent leaks. In Java, objects are instantiated on the heap and automatically managed by garbage collection.
