This question already has an answer here:I need to write a wrapper class that provides "get" methods for the fields of a data class. However, I don't know the syntax to write a "getter" to return a 2D array. For example:
I am searching a clean c++11 (up to c++17) way to write a function that simply writes fps to the output stream with given 'start' and 'stop' times (e.g. given an interval times). So I have this code, for example:
c++14 introduced generic lambdas that made it possible to write following:It is very clear that this generic lambda func works just like a templated function func would work.
I get these errors from GCC:Pre-decrement and post-decrement operators cause similar errors. No such errors with Clang. Any ideas what could be wrong or how to work around this?
I ran into the following oddity when making a mistake writing some code for trees. I've stripped down this example a lot so it is only a Linear Tree.
In a recent article I read that the following use of std::map::emplace might leak memory, but I do not see why:
I'm confused why the book I'm reading says that the following two declarations have the same effect:In the first declaration, the return type of max(a, b) could be the type of a, or the type of b. In the second declaration, the return type is the type of a. How...
Suppose, I have a structureand want to write function which reads field "name" from objects and return them as std::vector<std::string>. Is it possible to do this by variadic templates (or any non-iterative method). My goal is something like this:
I want to custom an Exception class, here's the code:I used Clion and the IDE give me a warning on the function what():exception specification of overriding function is more lax than base version
I am reading C++ Templates (2nd edition) and this is a snippet from the book:It is specified in the book that the declaration above is useless because N cannot be specified or deduced.
