Namespaces in C++ are used to organize an excessive number of classes for easier handling of applications. To access classes within a namespace, we need to use namespacename::classname. We can also use the using keyword, so we don’t have to keep using the full name. In C++, the global namespace is the root namespace. global::std … Read more

If we create two or more members with the same name but different numbers or types of parameters, this is called C++ overloading. In C++, we can overload: Methods Constructors Index properties This is because these members only have parameters. Types of Overloading in C++: Function Overloading Operator Overloading Function Overloading in C++ Function overloading … Read more

A programming language defines a set of instructions that are compiled together by the Central Processing Unit (CPU) to perform specific tasks. Programming languages mainly refer to high-level languages such as C, C++, Pascal, Ada, and COBOL. Each programming language contains a unique set of keywords and syntax used to create a set of instructions. … Read more
Boost unit testing framework (Boost.Test) is part of the Boost library. It is a fully-featured and extensible framework with various assertion macros, XML output, and more. Boost.Test itself does not include mocking capabilities but can be used in conjunction with standalone mocking frameworks (like gmock). If you are not familiar with Boost.Test, here is a … Read more
