I want to create some specific random, such that from 10 to 20. rand()%20; is create from 0 to 19

I need a function which would generate a random integer in a given range (including boundary values). I don't have unreasonable quality/randomness requirements; I have four requirements: I need it to ...

Possible Duplicate: Generating random integer from a range I am trying to create a program where the computer guesses a number the user has in his/her mind. The only user input required is whether ...

Usage of rand() is usually frowned upon despite using a seed via srand(). Why would that be the case? What better alternatives are available?

I've written a C function that I think selects integers from a uniform distribution with range [rangeLow, rangeHigh], inclusive. This isn't homework--I'm just using this in some embedded systems ...

One common way of choosing a random number in [0, n) is to take the result of rand() modulo n: rand() % n. However, even if the results returned by the available rand() implementation are fully ...

I have a stream of (uniform) random bits from which I'd like to generate random integers uniformly in the range [0,n] without wasting bits. (I'm considering bits wasted which are in excess of floor(...

I had an assignment that required us to generate a three digit number twice so a student can add them together and then check their work. I am still very, very new to C++ and my class regretfully ...

Because of the pigeon hole principle, you can't just use output = min + (rand() % (int)(max - min + 1)) to generate an unbiased, uniform, result. This answer to a similar question provides one ...

I am wanting to create a dice roller so that the user can choose a number of sides on a dice and it will randomise the response, My current code chucks out the same number all of the time. Sub ...

Assuming I can generate random bytes of data, how can I use that to choose an element out of an array of n elements? If I have 256 elements I can generate 1 byte of entropy (8 bits), and then use ...

This is not a duplicate of #11766794 “What is the optimal algorithm for generating an unbiased random integer within a range?”. Both its top-upvoted answer and its Accepted answer have to do with ...

I wrote a code which shows a question and 4 answers, ask to choose the correct one, and checks the choice. Now I would build a table which would contain 6 columns: question/a/b/c/d/correct_answer, and ...

I am developing a gaming platform that is subject to heavy regulatory scrutiny. I chose Math.NET because it seemed like a good fit. However I have just received this comment back from our auditors. ...

I have to write a c++ program and have a problem only with the following part: [...] for that purpose, you will need two random integral numbers from uniform distribution on the set {0,1,...,9} (...
