// Sample output

// Code to copy

#include<iostream>
using namespace std;

int funct(int);

int main()
{  
cout << funct(7)<<" "<<funct(0);
   return 0;
}

int funct(int n){
   int var=1;
   while(n>0){
       var*=n;
       n--;
   }
   return var;
}

if n=7 the above code prints 7! value as 5040.

7!=7*6*5*4*3*2*1
