Question

Using C++ program. Only C++.

The factorial of a nonnegative integer n is written n! (pronounced “n factorial”) and is defined as follows n! = n * (n – 1) * (n – 2) * … * 1 (for value of n greater than to 1) and n! = 1 ( for n = 0 or n = 1). Write implementation a function factorial with the following function prototype long factorial (long n); Write the main function that uses the factorial function to compute and output the factorial of n values 0..10.

Example output:

0! = 1

1! = 1

2! = 2

3! = 6

4! = 24

5! = 120

6! = 720

7! = 5040

8! = 40320

9! = 362880

10! = 3628800

Explanation / Answer

#include <iostream>

using namespace std;
long factorial (long n);
int main()
{
for(long i=1;i<=10;i++) {
cout<<i<<"! = "<<factorial(i)<<endl;
}
return 0;
}
long factorial (long n){
long product = 1;
for(long i=1;i<=n;i++) {
product *= i;
}
return product;
}
