The code size in recursion is smaller than the code size in iteration. Here, the termination condition is defined in the definition of the loop. The termination condition is defined within the recursive function. The format of iteration includes initialization, condition, and increment/decrement of a variable. There is a termination condition is specified. In Iteration, loops are used to execute the set of instructions repetitively until the condition is false. In iteration, there is a repeated execution of the set of instructions. Recursion is the process of calling a function itself within its own code. We are comparing both terms based on some characteristics. Now, let's see the comparison between iteration and recursion. C program to find the factorial of a number using recursion Let's see an example of finding the factorial of a number using recursion. Recursive functions are helpful in solving various problems such as finding the factorial of a number, creating the Fibonacci series, etc. Recursion code is shorter than iterative code however, it is difficult to understand. It is slower than iteration because of the overhead of maintaining of the stack. So, it is important to impose a termination condition of recursion.
Any function which calls itself is called a recursive function, and such function calls are called recursive calls.ĭuring defining the recursion, one must define an exit condition carefully otherwise, it will go to an infinite loop. In computer science, recursion is a process of calling a function itself within its own code. Recursion is said to be the process of repeating things in a similar manner. Before jumping directly to the comparison chart, let's first discuss both terms separately with an example of each. So, without any delay, let's start the topic. So, it is important to know the difference between them. Sometimes, the terms could be confusing to beginners. Both terms repeatedly execute the set of instructions but they are the different terms with different code structures, with the same end result. In this article, we will discuss recursion and iteration along with the comparison between them. Next → ← prev Difference between Recursion and Iteration
