Write a c++ program to solve the factorial problem x! by creating a function that calls itself'

Int factorial(int n)
{
   if (n <= 1) {
      return 1;
   }
   else {
      return n* factorial(n - 1);
   }
}

With recursive functions, always check that there is a certain end criterium. When n<=1, the recursion stops.

Hypothesis: volumes of both figures are equal.the volume of  figure 1 is: .the volume of figure 2 is: .since , you can conclude that and . so, .volumes of figures are equal only when an angle in the basis is right (then figures will be the same), in another cases volume of figure 1 is less than volume of figure 2.the hypothesis was not correct in all cases.
