hi all, i am stuck with this...........
as shown in the below...i am supposed to run it and generate some results from it. However, after compiling the codes, the blackbox turn out to be a clearbox and there is no result at all.

by right, i should be able to key in an input value, then the program will run and produces a set of output values..... i am not sure whats wrong with it..hope someone can just guide me. anw, i have found the test data online which is also attached below, this is the test data that i should be getting after running the program....
