What is difference between namespace and class?

Classes are data types. They are an expanded concept of structures, they can contain data members, but they can also contain functions as members whereas a namespace is simply an abstract way of grouping items together.

Without namespaces, for example, you wouldn’t be able to make a class named Console, as .
