Recursion and Iteration Programming

recursion Recursion in C is a process where a function calls itself to solve a problem It allows a complex problem to be broken down into simpler sub-

Types of recursion There are several different recursion types and terms These include: Direct recursion: This is typified by the factorial implementation recursion 3 ) People use recursion only when it is very complex to write iterative code For example, tree traversal techniques like preorder, postorder
