Answer 1

Answer:

huh what do you mean by that?? I don't know

Answer 2

#include <iostream>

int factorial (int);

int main ()

{

 int number;

 std::cin>>number;

 std::cout<< factorial (number);

 return 0;

}

int factorial (int a)

{int fact=1;

 for(int i=1;i<=a;i++)

       fact=fact*i;

return(fact);

}
