Answer 1

#include<iostream>

using namespace std;

int main()
{
    int n;
    long f = 1;
    
   cout<<"Enter a number between 0(exclusive) and 15(exclusive): ";
    cin>>n;
    
    while(n<=0 || n>=15){
       cout<<"Invalid input"<<endl;
      cout<<"Enter a number between 0(exclusive) and 15(exclusive): ";
       cin>>n;
   }
   
   for(int i  =1;i<=n;i++){
      f = f * i;
   }
   
   cout<<"Factorial of "<<n<<" is "<<f<<endl;
    
    return 0;
}
