And I´m here, yeah, you can ask me whatever about it, if I don´t know maybe I can talk with my classmates and help you, you little human, jajaja :).

#include <iostream>
#include <cmath>
 using namespace std;
int main(){
    int num, factorial= 1;
cout<<"Enter number to find it´s factorial: ";
cin>>num;
for (int a=1; a<= num; a++)
{
factorial= factorial*a;
}
cout <<"The factorial is:  over 9000 "<<endl; 
cout <<"Na, I´m joking, this is the real:  "<<factorial<<endl;
cout<<"Thanks for visiting us, see you "<<endl;
return 0;
}
