C++ programming Exercises practice with solution
What is C++ Programming Language?
C++ is a general-purpose programming language. It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation.
It was designed with a bias toward system programming and embedded, resource-constrained and large systems, with performance, efficiency and flexibility of use as its design highlights. Many vendors provide C++ compilers, including the Free Software Foundation, Microsoft, Intel, and IBM.
The best way we learn anything is by practice and exercise questions. We have started this section for those (beginner to intermediate) who are familiar with C++ programming.
Hope, these exercises help you to improve your C++ programming coding skills. Currently, following sections are available, we are working hard to add more exercises .... Happy Coding!

C++ Programming: Tips of the Day
Why are non member static constexpr variables not implicitly inline?
The point here is that constexpr int x = 1; at namespace scope has internal linkage in C++14.
If you make it implicitly inline without changing the internal linkage part, the change would have no effect, because the internal linkage means that it can't be defined in other translation units anyway. And it harms teachability, because we want things like inline constexpr int x = 1; to get external linkage by default (the whole point of inline, after all, is to permit the same variable to be defined in multiple translation units).
If you make it implicitly inline with external linkage, then you break existing code:
// TU1 constexpr int x = 1; // TU2 constexpr int x = 2;
This perfectly valid C++14 would become an ODR violation.
