I am trying to test the random integer generator in a program to make sure that it gives the type of output that I am looking for. I expect it to generate (p<>q)<10 slightly less than 1/8 of the time and (p=q)<10 slightly more than 1/8 of the time, 9<(p<>q)<20 slightly less than 3/8 of the time, and 9<(p=q)<20 slightly more than 3/8 of the time. Regardless of my expectations I would like to see how the numbers actually come out, and to that end was attempting to test the test the code, but I can not get it to generate (print) any numbers. I am sure that I have made an error somewhere in the code, but I can not find it and am not getting any error messages. Thank you for any and all help.
