Calculating the Factorial of a Number
Explore how to calculate the factorial of a number in C++ using recursion. Understand the base case for stopping recursion, handling invalid inputs, and how the function calls itself to compute factorials. This lesson guides you through writing and running a recursive factorial function for non-negative integers.

Introduction
Let’s consider the example of the recursive factorial function. In this lesson, we will calculate the factorial of a number n denoted by n!.
📝 The factorial of a given number is the product of the number by all the numbers smaller than it until it reaches 1.
📝 We can only calculate the factorial for the non-negative integers.
