Factorial with recursion
WebRecursion has many, many applications. In this module, we'll see how to use recursion to compute the factorial function, to determine whether a word is a palindrome, to compute powers of a number, to draw a type of fractal, and to solve the ancient Towers of Hanoi problem. Later modules will use recursion to solve other problems, including sorting. WebOutput. Enter a positive number: 4 The factorial of 4 is 24. In the above program, the user is prompted to enter a number. When the user enters a negative number, a message Enter a positive number. is shown. When the user enters a positive number or 0, the function factorial (num) gets called. If the user enters the number 0, the program will ...
