I read the question as "I've got this function and it does what I expect but I don't understand the code". On that basis... The function creates a factorialfor the input number 'n' (i.e. 1*2*3*4.....*n) The first 2 lines checks to see that the input is less than 2 and, if so, returns a value of 1 The rest of the code counts down from n to 1 multiplying f by n at each iteration. If I guessed the right question, reply to the post for further clarification. Steve On 11/01/2013 16:33, kwakukwatiah@gmail.com wrote: > > > -----Original Message----- From: K.
