Many programming languages either have keywords like or and and used for logic, or equivalent operators such as || or && - which are referred to as "logical or" and "logical and" respective...
When doing something simple such as this int a=1; int b=2; int c=3; printf("%d\n", a + b * c); then I was told that operator precedence guarantees that the code is equivalent to a + (b * c)...
I am trying to capture the content outside square brackets in groups, using this regex: (.*)\[.*?\](.*) And it works perfectly for a simple string like this: testing_[_is_]_done This is the...

These are the methods I know of: Set the form's target attribute to _blank. Add submit event listeners (e.g., this SO thread). In the proprietary web app that I have to work with, every form...
I'm trying to use the "hexagonal architecture" and "domain-driven design" paradigms together, in a Java application using Spring. I understand that my application should have a structure with 3 la...
In C++11 the nullptr keyword was added as a more type safe null pointer constant, since the previous common definition of NULL as 0 has some problems. Why did the standards committee choose not to...
A class might calculate static variables during instantiation, which are then used by various functions. A common technique to optimize function performance is to precalculate expensive variables u...

In my desktop application developed in C++, I am encountering an issue where pressing the Ctrl + X, Ctrl + Shift + X, and Ctrl + D shortcut keys triggers a system sound. I would like to suppress o...
This question is adapted from a question I just helped fix up on Stack Overflow. I'm giving a different motivating example which I think will make it clearer what the requirements are and why a n...
Unless I am mistaken, myList.Select(a => a).ToList() initializes the resulting list to the capacity of myList.Count. Does myList.Where(a => true).ToList() do so or does it build up from the i...
