Quiz on function declaration and overloading, operators and statements, values and arguments, macros, namespaces and exceptions.

Functions: A function is a block of code that performs a specific task. Functions can take input parameters and return output values. They are used to organize code and make it more reusable.

Namespaces: A namespace is a way to organize code into logical groups. Namespaces can be used to avoid naming conflicts and to make code more readable.
To define a namespace in C++, you use the following syntax:
C++
namespace namespace_name {
  // code in the namespace
}
The namespace_name is the name of the namespace. It must be a unique identifier within the scope in which it is defined.
The code in the namespace is the code that is contained in the namespace. It can contain any valid C++ code, including statements, expressions, functions, and other namespaces.
To access a member of a namespace, you use the following syntax:
C++
namespace_name::member_name;
The member_name is the name of the member that you want to access. It can be a function, variable, class, or other namespace.

Exceptions: An exception is an object that is thrown when an error occurs in a program. Exceptions can be used to handle errors in a more controlled way.
To throw an exception in C++, you use the following syntax:
C++
throw exception_object;
The exception_object is the object that is thrown. It can be any type of object, but it is typically an object that is derived from the std::exception class.

The exception_type is the type of exception that you want to catch. It can be any type of object, but it is typically an object that is derived from the std::exception class.
The exception_variable is a variable that stores the exception object that is thrown.
The code that handles the exception is the code that is executed when an exception is thrown.
