In this case, you have a total of 52 balls in the urn. The chance of picking a blue is 50/52, and a red is 2/52. The total probability is 50/52 + 2/52 = 52/52 = 1 (the ball will always be either blue...

The link in my previous reply suddenly doesn't seem to work so I supply an example. It is based on the recipe: "Generating pseudo-random numbers" in Modern C++ Programming Cookbook, 2nd ed. by Marius...

If you have the possibilities 0.8, 0.1, and 0.1 you think of them as three intervals,

1: 0.0 <= x < 0.8
2: 0.8 <= x < 0.9
3: 0.9 <= x < 1.0

Then you draw a random float x between 0 and 1, for...

Well, according to the link in my previous post, according to the C++ standard, a reinterpret_cast should work,

"3) A value of any integral or enumeration type can be converted to a pointer type."...

As a last resort, there's always the reinterpret_cast,


wpAddress = reinterpret_cast<WORD*>(nAddress);

You don't have to sort anything. Of course you can store all distances and then sort them to find the shortest. But you really just need to keep track of one distance, the shortest_so_far. Each time...

Do you want to find the shortest cell distance between two sites? Then you just calculate all possible cell distances one by one and keep the shortest so far. You don't need a data structure for that.

Start with a minimal program that works. In this case just a main method that prints "Hello world". Then add code, little by little in incremental steps making sure it works after each step. So you...

Well, what I can see from the code in #1 you are copying already as part of the sorting process (swapping of records),

If the problem is that you want to co-sort the second array with the first, one way is to introduce a temporary std::vector of std:: pair.

In each std:: pair you combine a PiInfo object with its...

Well, I'm sure there is some ugly trick to do it but using the preprocessor is better I think because then you don't break the C++ language itself. The preprocessor allows you to select which parts...

You could use the preprocessor to define a macro that looks like this while testing,

You could replace the loop with 16 straight assignments like,
