Is there a better (more memory efficient and safe) way to pass the 2-D array via the constructor below? Is it necessary/advantageous to utilize a ptr variable? What if the size of the array (both dimensions) is not predetermined?
#include <iostream>
#define MYNUM 4
class myClass {

First I'm not sure what this is called formally but whatever.
Basically I need to form "wildcard buckets". I think the best way to explain what I need to do is to take an example. For instance, say I have the three words "aaa", "aab", and "baa".
Let me use * as the wildcard. Then from aaa I can...

I will be inserting a new text line in a setup.py file, this new line will contain text, and is part of the REQUIRED_PACKAGES. I parsed the

I need your review o below class implementation in terms of efficiency, memory consumption and new features of C++11/14/17 that can be used.
Basically I have written a matric class for addition, multiplication and scalar multiplication.
Here goes the code:

if ($v->getMedical()) {
$visitorHasMedical = $v->getMedical()->getMedCon() == true; // $visitorHasMedical will be false if "falsey" i.e. empty string or NULL
} else {
$visitorHasMedical = false;
}
Where getMedical() is a OneToOne Doctrine relationship that might not exist.

The question is mainly about database design. Is it OK?
I feel uncomfortable about having 2 separate WordTraining and SyllableTraining tables and about too simple design (not much normalized). Maybe there are any other issues.
My web-app teaches kids to read syllables and words.

Is there any quicker method than using a for loop to find the first instance of a formula in a cell?

It looks like the syntax highlighting has recently changed for VBA (I would post a sample but I don't think meta does code highlighting...)
Here's an image to preserve what I'm seeing, tagged with lang-vb which is the default extension for the VBA tag:

I have two python libraries, let's call them lib and extended_lib, that provide a very similar public API. To be more specific, extended_lib enriches the API of lib with new features and functionality; it also modifies the behavior of some functions that are also provided in lib (e.g. get_version...
I have a weather app that allows the user to save Cities (with nickname and zip) into a room database. I'm using mvvm and livedata to observe the list of cities and update the recyclerview accordingly. I then perform an api call for each item in the recyclerview which to me seems wrong. It works ...
I asked this question on Stackoverflow, but thought it might be a better fit here.

I am beginning to learn about object oriented programming in my programming class, and to make sure I had all the ideas down, I made a small palindrome checker program. It works by checking if the letter on the opposite side is the same.

Today the code just generates an random hostname and appends it to a domain (tlds). Eventually I intend to add functionality to attempt to resolve the fqdn and retrieve nameserver information for each domain.
On certain runs findHint() doesn't run all 5 times like it should.

I wanted to ask this here because what I wanted to originally do felt like a really Pythonic method. I want to be able to use the syntax:
d = {'a':{'c':4},'b':2}
with d['a'] as item:
print(item['c'])
but found that Python doesn't allow for using lists, dicts, etc. as context managers.
So ...
