Can you list the main areas or sections included in the heap structure?

In the heap structure in the context of memory management in C#, several main areas can be distinguished:

• Large Object Heap (LOH) — an area for large objects (usually over 85,000 bytes), which are allocated separately to avoid frequent fragmentation.
• Small Object Heap — an area for small objects, which are allocated and managed more efficiently.
• Generation 0, 1, 2 — generations into which the heap is divided for garbage collection optimization: objects initially go to Gen 0, and if they survive collection, they move to Gen 1 and then to Gen 2.

Thus, the heap in .NET is organized considering object sizes and generations for efficient memory management and garbage collection.
