how long a fence could be built with x number of posts
No of posts * diameter of 1 post? Regards, Nish

Currently working on C++/CLI in Action for Manning Publications. Also visit the Ultimate Toolbox blog (New)No. The setup for that type of question is: "you have X posts, that need to be spaced D distance apart (for the cross peices). How long of a strait fence can you make?" The common wrong anser is X*d. The correct answer is (X-1)*D. If you're confused about why, set X = 2, and draw the fence |-|. This's why an off by one error is also called a fencepost error.

Yep, that's when there is spacing. If you assume no spacing, and that the posts are fixed into the ground - it's n * diameter. That's how I mentally pictured a fence :-) Regards, Nish

You'd've gotten it wrong on the test then. :)

Nope, when I read the "spaced" part of the question, I'd know that fences are not made the same way in all parts of the world :-) Regards, Nish

A fence made entirely of posts? Yeah, i could see that... but it'd get real pricey (unless you were building it in the middle of a heavily wooded area and could just cut your own posts as-needed). Have you seen many of these?

In Kerala (my state in India), most fences are made of concrete - in the towns. In the villages, people do have fences that are essentially a stack of trees - living fences :-) The trees are planted one after the other in a line to form the fence. There's no spacing between each tree. Regards, Nish

A carpenter was in a terrible hurry. He had to work as quickly as possible to cut a very heavy 10 foot plank into 10 equal sections. If it takes 1 minute per cut, how long will it take him to get the 10 equal pieces? "C++ will solve any problem."
