As you can see, it only returns a function call and nothing more than that. It can just forget them and concentrate on the recursive function calls. The interpreter need not remember the values of any variables outside the function calls. We need to choose based on the need, and in some cases, we use Recursion for the return values. If not, we will be left with either while and do-while loops or Recursion. When we know the number of iterations, we use a for loop. When we use loops, we need to know how many times we need to iterate the loop as in a for loop. Loops are used to perform repetitive tasks, and so are the functions? What is the difference, and how to know when to use what? So, we write a function, say factorial for N, in which we call the same function again for N-1, which is repeated till N=1 We need to write a program to find the factorial of a number. Just like this, when we need to write a code for a complex problem, we break it into smaller and repetitive parts. When we want to perform a complex task, we generally break it into smaller tasks doing them one after the other decreases the burden and the complexity. Now, we want to check if 2 is even or odd, so we call the function by giving the argument as 2, which the function will replace at num and the function is carried on it. We defined the function and then wrote the logic in it. Here, evenORodd is the function we defined to check if the given number, num, is an even or an odd number.
