WebFeb 16, 2024 · Approach 1: Using For loop. Follow the steps to solve the problem: Using a for loop, we will write a program for finding the factorial of a number. An integer variable with a value of 1 will be used in the program. With each iteration, the value will increase by 1 until it equals the value entered by the user.
WebConsider a factorial. The factorial function is defined like this. It takes an n Int and it gives you an integer result. It says if the argument is zero, then the factorial of zero is one. Otherwise the factorial is the number n times factorial n minus 1. Let's consider factorial 4. That would be the body of factorial that we see here. There ...
