randoma | User-friendly pseudorandom number generator | Runtime Evironment library

I made two classes the first one will return a random number and the second class will take the same random number with +1 but it's not working

I have a numpy array that I would like to concatenate the columns into a single value for the row. Below is what I have tried so far.

I have a multi-thread QT application that sometimes need a random alphanumeric string from one of its threads (some threads start at application startup, others start or die during lifetime), and I would like to obtain that by calling a function defined in a common header, to avoid code replication.

Here there's a code snippet:

I am trying to generate data for a project. The data needs to be generated randomly from predefined lists. Essentially, I have real data but it's very small. In order to build some classifiers (decision tress, Support Vector Machines and Naive Bayes), I want to produce 100,000 observations.

I am new to coding (I can do rudimentary things in Matlab and R) and initially tried to do this in Excel, however, the RANDOMA function generated very equally distributed data. To be more specific, I am using 5 demographic pieces of information to predict which retailer a customer will select, e.g. retailer A, B or C. The lists for the demographic information is below:

1) Age group (18-24, 25-34, 35-44, 45-54, 55+) 2) Gender (male or female) 3) Income group (<£10k,£10k-19.99k, £20k-£29.99k, etc.) 4) Region (London, Wales, Scotland, Nothern Ireland, South West, etc.) 5) Type of job (Full-time, part-time, student, etc.)

When I tried to randomly create 100,000 observations (each observation randomly selected 1 from each of the 5 lists), they were almost equally distributed between them. Even worse, the value you I randomly assigned to the retailer (A, B or C) was also equal.

The idea is to split this randomly generated data into training and test data, so I can build some models and test their suitability.

I'm trying to use UPDATE to update 3 different columns in my table(stores). I would like to add a openingTime, closingTime, and phoneNumber...but I want them added via an storeId, which already exists in the table. Do I need to make an individual call for each entry based on storeId. Or is it possible for me to make a single call to the table and loop through each storeId?

Here's what I have so far.

I'm supposed to fill this array of string with all the letters from the alphabet ex: "a","b","c","d", etc.

I've been staring at this for an hour and I confused on where to start? I was just introduced to arrays today in class so excuse my ignorance . Usually isn't an array filled like this String[] randomA = {'a','b','c'} etc. So I'm confused on how to fill it with a loop. Can someone tell me why they start with for ( char ch = ) in the for loop and point me in the right direction on how to start?

Goal state: I'm supposed to display a result where by randomized e.g. Set S = {dog, cow, chicken...} where randomized size can be 1-12 and animals cannot be replicated so once there is cow, there cannot be another cow in Set S anymore.

Error: I've been displaying a correct randomized size of 1-12. However I have duplicated animals even though I tried to check whether the animal exist in set S before I insert it into Set S.

UPDATE: I couldnt get it to run after the various updates by stackoverflow peers.

Constraints: I have to use pointers to compare with pointers - dynamically. "Important Note All storages used for the arrays should be dynamically created; and delete them when they are no longer needed. When accessing an element of the array, you should access it via a pointer, i.e. by dereferencing this pointer. Using the notation, for example set [k] or *(set + k) accessing to the kth element of the set is not allowed."

Do hope to hear your advice, pals!
