Algorithm

·                     Start

·                     Declare n, j as integer

·                     Write("the number")

·                     Read("the number”)

·                     Read(" the factorial of the number”)

·                     Stop

·                     Declare fact(int n), result as integer

·                     if(n==0)

·                     result=1

·                     else

·                     result=n*fact(n-1)

·                      return (result)
