Algorithm

·                     Start

·                     Declare i, fact=1, num as integer

·                     Write(“the number”)

·                     Read(“the number”)

·                     if(num<=0)

·                     fact=1

·                     else

·                     for(i=1;i<=num;i++)

·                     fact*=i

·                     Read(“Factorial of number”)

·                     Stop
