What Is Heap in Programming?

A memory area used for dynamically allocated objects whose lifetime is managed manually or by a garbage collector.

In practice, heap becomes easier to use when you trace the input, the state it affects, and the output another part of the program can observe.

Use heap in a small example first, then vary one input and explain the resulting behavior before you run the code.

Remember heap as a specific relationship in a program, not as an isolated definition to memorize.
