**Program to find factorial of Number in C++** : ,Hi,Today we make Program About factorial.The factorial of a positive integer n is equal to 1*2*3*…n. You will learn to calculate the factorial of a number using for loop.

What is a Factorial of a number â€˜nâ€™?

The factorial of a number â€˜nâ€™ is the product of all number from 1 upto the number â€˜nâ€™ it is denoted by n!. For example n=5 then factorial of 5 will be 1*2*3*4*5= 120. 5!= 120

# C++ Program to Find Factorial

#include <iostream> using namespace std; int main() { unsigned int n; unsigned long long factorial = 1; cout << "Please Enter the Number: "; cin >> n; for(int i = 1; i <=n; ++i) { factorial *= i;} cout << "Factorial of " << n << " = " << factorial; return 0; }

**Output of Program**

Enter a positive integer: 12 Factorial of 12 = 479001600
