Hi , You can solve the problem both recursively and iteratively : Recursive :
Class FactorialCalculation { private int finalFactorialValue = 1 ; // Class Variable
, setting the initial value Public static void Main() { int myvalue = // Take
Input from UI or Where ever ;
if ( myvalue > 1 && myvalue > 0)
CalculateFactorial(myvalue) ;
MessageBox.Show(finalFactorialValue.ToString()); } public void
CalculateFactorial(int value) { if ( myvalue > 1) { finalFactorialValue = (myvalue) *
CalculateFactorial(myvalue-1) ; } return (finalFactorialValue); } } infact
this a much faster way than iteration as in case of interation it's simple for loop
that keeps on passing values to and fro and keeps calculating , For Validations , u
can just check through regex that value entered by a user is an integer then only
continue else publish an error message , hope it helps , regards , Mrinal
