At the moment I'd like recommendation where I can change and what I can use to improve on simplicity and modularity. If I'm practicing good naming conventions as to provide clean readable code. Any critique is much appreciated.

I've been working through the book Head First C# and this is an exercise from chapter 7, which is about interfaces and abstract classes.
I'd like a review on any and all aspects. My code ended up quite a bit different than the book's solution, because it's a few years old and I think "holds bac...
I am pretty new to writing c. It would be great to get some feedback on whether best practices are being followed.

So I've been working on a generator for Pascal's triangle in Python. Now, I wouldn't call myself a Python god, so my program is a lot longer than the very confusing ones on the internet. It's more of a logical approach to creating the triangle.
Here's the program:

Question-
My approach-
I noticed that the minimum of a row is when t=k-one of the numbers of that row.
Suppose in the above sample case,
t=4 which is 6-2.
Since we have to find the minimum maximum testing all k-no will give the solution.
Any tips to improve this technique as for cases where eac...
I made a simple template matching app and was wondering if there are any improvements to be made with the code

Good day. I have written a piece of code that finds the next Prime Number after a given number (input), but here I'm seeking to optimize it, or, more importantly speaking, make it run for any number until 1000000000 in 2 seconds or less.

Is there a more correct way to transform an array based on a condition rather than just looping through it?

for x in x_array:
if np.abs(x) <= 3:

else:
yield 0
