I have a few options including this one:
DIR *Dir = opendir("/path/to/directory");
while (readdir(Dir));
long NumItems = telldir(Dir);
Is there a faster way than that? How do I find the number of items in a directory in C?
Hi :) I am a beginner coder who just learnt C++ and I wanted to apply it in projects to solidify my learning process. However, I only took a short tutorial before trying this out hence I'm pretty unsure about my C++ coding practices and I would like to know what areas I can improve on - and perha...
I am learning about clean and maintainable code. I heard that functions should be no more than 20 lines long (preferably 5 - 10 lines). I have come across this Bob Martin quote where he said:
“The first rule of functions is that they should be small. The second rule of functions is that they sho...
This is my code:

I don't know why but it is showing false.

I've written the following custom event system module and I'm planning to use it in production in the future. Before I do that, I'd like to ask for general suggestions on how to improve it. Thanks a lot.

function on(event, callback) {

For self learning purpose, I have created some xUnit unit test for these 2 Atm classes. At the moment, data is store in the in-memory object. This version is extended from previous version. For brevity, I excluded Withdraw method and ThirdPartyTransfer

Consider this simply function fileContains, (File, String) -> Boolean.
Gradle complains that it is ambiguous because it could be interpreted as a parameterless closure expression or an isolated code block. Why? How can I fix this?

Java beginner here! As part of practicing programming, I've run into Pascal's triangle. I tried to implement a solution where the triangle is printed like so:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
...
So roughly right-sided. My solution though runs into multiple errors, and although I would appreciate...
Here I'm posting my Java code for the skyline problem. If you have time and would like to review, please do so, I'd appreciate that.
Problem
A city's skyline is the outer contour of the silhouette formed by all
the buildings in that city when viewed from a distance. Now suppose
you are given the...
result.POINTS = { POINT: [] };

I've made this Function gradient() that returns a list of rbg of all the colors in an order.
Issues:-
What should be the condition for while loop to stop the loop. Though b == 0 in the last elif block works fine.
How can I reduce the code of the function keeping the functionality the same. Like...
I'm a beginner ! and I want to implement a quick sort algorithm , but my code doesn't give a wrong answer.

A trie for handling strings for an autocomplete dictionary. This passes my fairly casual tests, though it's always possible that there are broken edge cases, but I'm mainly concerned about design and efficiency: is this a sensible way to implement this data structure? (In particular, is it sens...
I am attempting to make an unbeatable Tic Tac Toe game using a simplified minimax algorithm. The code looks like this:

Here is a very simplified example of my code using Cars so I don't have to explain my domain details.
The primary class concerned is the CarGenerator class. This takes a CarConfiguration object. It has a various properties of Car<T>. You can see its usage below:
