A static data member of the class may be fully defined within the class definition if it is declared inline. For example, the following class may be defined in a header. Prior to C++17, it would have been necessary to provide a .cpp file to contain the definition of Foo::num_instances so that it wou...

We're going to integrate the AlmostEqualToConstraint with the fluent NUnit interfaces, specifically the Is one. We'll need to extend the NUnit provided Is and use that throughout our code. public class Is : NUnit.Framework.Is { public static AlmostEqualToConstraint AlmostEqualTo(int expected,...
