I created a script to scrape this website and gather the eclipse data (date, type, and location):
class Eclipse():
def __init__(self, eclipse_date, eclipse_type, eclipse_location):
self._eclipse_date = eclipse_date
self._eclipse_type = eclipse_type
self._eclipse_location = eclipse_l...
What i'm hoping my code is doing is instead of making 99 comparisons on every pass of a 100 element array, it will now make 98 comparisons on the second pass, 97 on the third pass and so on and thus decreasing the iteration through the array.
Here's my code
st.Reset();
st.Start(...
My spreadsheet has a column (and list of properties following each row) of about 100 entries of people. This script is supposed to detect when a cell in the column is changed and sort every row on the sheet by the column in ascending order (that's what sort() does). After saving the script, going...
I'd like to write a function to split strings in C++ to check my template learning. I've also read some relavent questions in this site but most of them don't use templates or string_view. A related question in StackOverflow I asked is here.
My goal is to write a function such that:
The functi...
Please note that not every question about non-working code on Code Review would be a good question on Stack Overflow.
In fact, there are very few questions, which are closed with the "non-working code"-reason, that would be good questions on Stack Overflow.
If a moderator, if I see a question t...
I am writing an interpreter for a simple mathematical programming language.
Below is a simple program written in it that prints 41.22:
let $x = 35; # This is a comment
$x + 6.22;
Below is the code for the lexer. As this is my first attempt at writing an interpreter, I would appreciate any gen...
The exercise is from a Java-course in which I'm enrolled.
The classes Book and APIResponseParser were provided by the instructor.
For Book I had to add just a few getter- and setter-methods.
Main work was the instance-version of parse().
It shall extract specified tag-values from a given XML-...
Too many subclasses
Neither of these approaches are very good, as both of them have more subclasses than necessary. Why does EightsCard extend Card ? What if you wanted to implement some other card game? (There are quite a few, you know...) Would you make one subclass for each card game? Please ...
I am trying to implement an efficient collision detection between a line joining two points and a bitmap mask.
Example:
Currently I am using Bresenham's line drawing algorithm to draw each pixel of the line between the two points and comparing that pixel with the bitmap (If the pixel is black...
I have been writing a program to print to the screen a description of a directed graph** from a file named graph-file.txt. That description includes the number of vertices (7 in my case), and the edges in the graph (the vertices numbered 0-6):
7

Given an array of integers arr where each element is at most k places
away from its sorted position, code an efficient function
sortKMessedArray that sorts arr. For instance, for an input array of
size 10 and k = 2, an element belonging to index 6 in the sorted array
will be located at...

I'm going to write a Huffman Coding implementation, and decided to write from scratch a priority queue to help out. I've never written a priority queue before, in any language, so this was interesting.
After mulling over the design for a bit, I finally settled on a linked list design. The queue ...

I am trying to create a validator abstraction layer. These are the points I am trying to achieve:
My abstraction should be open for extension but closed for modification
The clients should not have a if...else block to handle success or failure scenario.

I'm trying out some different programming styles to experiment with the new c++ concepts.
Within the experiment I was looking into how constexpr could be helpful for writing unit tests at compile time.
Below, you can find the code which represents a single cell in a sudoku, where this cell is r...

I am new to writing ASM and reading code. I am not understanding why "BNE -" (line lc013) means in the context of the routine.

This little algorithm I wrote computes all the interpolations between several points.
E.g. if we have three points P_1, P_2, P_3, then my algorithm picks up 3 weights and launches the linear interpolation between these points (which is another subject, out of the range of this question).

I've been using logging librarys recently and somebody told me to try and write my own. I've kept it minimal but the onyl drawback is I can't log in static classes, due to TClass.
Looking for constructive criticism on how to improve it, thanks.
