This question is a direct follow-up #1 of my previous question:

There were too many errors which I didn't see at the moment and I tried hard to fix them up now. I would like someone else (than myself) to actually review the code this time.

I don't mess around a lot with templates (or with GTK), but today I wrote something and would like to know how it can be improved, and hopefully clarify a few things in the process.
So, Randolfi() is a function template which returns a random number. A range can be specified as arguments.

I have implemented a dynamic array in C. I am a beginner in C so any constructive feedback about improving the implementation would be greatly appreciated.

I wrote a C++ plugin that retrieves screen pixel. It works on Windows and Android. I noticed that dllexport is only required on Windows but not on Android and causes error on other platform other than Windows. I fixed that by using #if macro to make it use dllexport only on Windows.

Very new to learning python in my first semester of college, I could use some help.
Instructions, to write a code that:

Add the total amount from each saving.

This post was posted by an acquaintance with whom I am directly related. I'm helping her ramp up on Python. Usually, I wait for the community to answer the questions posted by her (since it gets her objective feedback from the best folks out there), but since this post didn't have any feedback fo...
Two Sum Problem:
Given an array of integers, return indices of the two numbers such that they add up to a specific target.
You may assume that each input would have exactly one solution, and you may not use the same element twice.
Example:
Given nums = [2, 7, 11, 15], target = 9,
Because num...

I'm making an randomized image appear on every reload of my homepage. This image gallery will eventually become very large, so if there's a way for me to use the images (currently from Imgur) without having to write up all of the separate links up I'd be delighted.

I got this question in an interview:
Given an array find two numbers that have the maximum sum which is also an element in the array
For example: 6 10 12 34 41 16
Output: 16
I could come up with a naive algorithm with time complexity O(N2). Is there a more optimized approach?

Let's assume we have an array that contains the following elements:
-1, 0, 0, 1, 0, -1, 0, -1, 1
I would like to count the combinations of consecutive elements such that
-1,0 & 0,0 & 0,1 & 1,0 & 0,-1 & -1,0 & 0,-1 & -1&1
In this case:
The count of -1,0 = 2
The count of 0,1 = 1

There are sometimes situations where you have a couple of related classes with static fields or properties but you cannot access them via T because you cannot define interfaces for static memebers.
I thought I write a helper that by utilizing dynamic allows me to do that anyway. It is implemente...
I hope this is the right place to ask but what maybe the consequences of using two versions of singalR in a single application on shared views.
I would think it depends on the usage but how otherwise it will impact the application use?
In the following class, I would like to change the way I call the methods in a better way. As you can see, I have to call each method and store its returned value into a variable and then pass it to another method.

I typically try to avoid using ! in if-statements, because (to me) it seems easy to overlook. So, I'll usually just spell it out instead, ex: if (done == false) instead of if (!done). While that makes the intention more obvious, it doesn't read very fluidly.

I am trying to have smarter classes where possible. So I would prefer:
class Age(val years: Int) {
assert(years >= 0 && years < 130)
}
class Person(val name: String, val age: Age) {

}
over:
