Question
**Question:**

In C, using malloc to allocate memory for a linked list uses which memory allocation scheme?

- ○ Heap allocation
- ○ Static allocation

**Explanation:**

The question asks about the type of memory allocation used when `malloc` is employed in the C programming language to allocate memory for a linked list.

- **Heap Allocation:** This is the allocation scheme used when memory is dynamically allocated at runtime. Functions like `malloc`, `calloc`, and `realloc` provide memory space from the heap. It allows for flexible memory management and is suitable for data structures like linked lists, where memory needs can change during execution.

- **Static Allocation:** This occurs when memory size is defined at compile time. Memory is allocated in a fixed amount and cannot be increased or decreased during runtime, typical of arrays with predefined sizes.

When `malloc` is used, it results in heap allocation.

In C, given:

```c
typedef struct Node {
    int Data;
    struct Node *Link;
} NODE_T;
NODE_T *NPtr, *Top = NULL;

int Count;
for (Count = 3; Count < 6; Count++) {
    NPtr = malloc ( sizeof(NODE_T) );
    NPtr->Data = Count * 2;
    NPtr->Link = Top;
    Top = NPtr;
}
```

What list is created?

- a) Top -> 6 -> 8 -> 10 -> NULL
- b) Top -> 6 -> 8 -> 10 -> 12 -> NULL
- c) Top -> 8 -> 10 -> 12 -> NULL
- d) Top -> 10 -> 8 -> 6 -> NULL
- e) Top -> 12 -> 10 -> 8 -> 6 -> NULL
- f) Top -> 12 -> 10 -> 8 -> NULL
