What are the differences between iterative and recursive programming in C?

What are the differences between iterative and recursive programming in C?

Iterative programming uses loops to repeat code, while recursive programming calls a function within itself. Each has its use cases.

Can you give me an example of both in C?

Sure! For iteration, you might use a for loop to calculate factorial. For recursion, you would define a function that calls itself.

Which method is more efficient?

Iterative methods are generally more memory efficient, while recursion can lead to stack overflow if too deep. It depends on the problem.

When should I use recursion instead of iteration?

Use recursion when the problem is naturally recursive, like tree traversals or when the solution is simpler to express recursively.
