What is iterative traversal in C++?

Can you explain what iterative traversal means in C++?

Iterative traversal in C++ refers to the process of visiting each element in a data structure, like an array or a linked list, using loops instead of recursion.

How does it differ from recursive traversal?

In recursive traversal, the function calls itself to visit elements, while in iterative traversal, we use loops to achieve the same result, which can be more memory efficient.

Can you give me an example of iterative traversal in a linked list?

Sure! Here's a simple example:

struct Node {
    int data;
    Node* next;
};

void iterativeTraversal(Node* head) {
    Node* current = head;
    while (current != nullptr) {
        std::cout << current->data << " ";
        current = current->next;
    }
}

What are the advantages of using iterative traversal?

Iterative traversal can be more efficient in terms of memory usage, as it avoids the overhead of multiple function calls and stack space used in recursion.
