C++ Program to Find the Factorial of a Number Tutorial

In this Tutorial you will learn to write a C++ Program to find the factorial of a number using Iterative Method ( for loop ).

The factorial of a positive integer n, which is denoted as n!, is the product of all positive integers less than or equal to n.

That is n! = n * (n-1)*(n-2)*....*3*2*1

So 4! = 4 * 3 * 2 * 1 which is equal to 24.

Factorial for the numbers 0 and 1 is 1. That is 0! = 1 and 1! = 1.
For negative numbers factorial value doesn't exists.

Please can you do a video on how to design and implement an algorithm for constructing Canonical LR (0) items and SLR parsing table for a Grammar G and use same to implement your chosen grammar.

Hello, guy. I don't know if you're taking requests, but there's a portion of a CS50 problem that requires finding a cycle in a directed graph. Could you do a video on that for Clang or for Depth First Search? Cause that section of the problem is ruining me, and another Youtuber called it "the most difficult function you'll have to write in the entire course".

How do you modify the code to only accept whole numbers?
