Often I'm in a situation where I need a simple RAII wrapper, but I wouldn't want to create a whole new class for this for many reasons including time constraints and organization problems. My quick-n-dirty solution is the following.
In the process of trying to work out a solid game loop in SFML I came across this issue which I can't seem to figure out. I was able to strip out all of the SFML code and still see the issue with clock() in time.h. Then I went further...
I have a struct C which gets initialized with a variable number of instances of struct A and struct B. E.g.:
Consider this code (demo):A structured binding to a copy of a const c-array are declared const by Clang and non-const by GCC.
my task is output all ten-digit numbers, where the numbers don't repeat. And I first I am using something like this:
I have a very simple template function to compare the rank field of two structs:This worked fine, until I compiled with -std=c++11. Now, I get the error
I am doing a .NET MVC tutorial. With that being said, I've came across code like this:Index view for Movies looks like:
Suppose that we have the following two inequalities inside a member functionandAre they guaranteed to be true? (They seem to be true in a few cases that I checked.)
I'm trying to understand better how memory works in .NET, so I'm playing with BenchmarkDotNet and diagnozers. I've created a benchmark comparing class and struct performance by summing array items. I expected that summing value types will always be quicker. But for short arrays it's not. Can anyone explain that?
Consider this example on Compiler explorer.Basically, we have this code snippet:If we compile this with GCC's libstdc++ (using either clang or GCC), we get the expected compile error:
