It is already past due. I have been working on these for 2 weeks and getting nowhere. I am using windows 7 64. Not sure what you mean by dev tools.
If you are asking about a compiler, I have been using a freebie on line. Here is the link.
For the second program.I added a 10 times "for" loop. And got the same answers all 10 times. How can I throw a change in there so that every time I got truly different answers? I think I may be able to add to the first one a means to input different miles driven to change it up. Otherwise you did a GREAT JOB!! Thank you so much!
