C++ allows overloading of operators, thus allowing us to assign multiple meanings to operators. The input/output operators << and >> are good examples of operator overloading. Although the built-in definition of the << operator is for shifting of bits, it is also used for displaying the values of various data types. This has been made possible by the header file iostream where a number of overloading definitions for << are included. To define a task to an operator, we must specify what it means in relation to the class to which the operator is applied. This is done with the help of a special function, called operator function, which describes the task. The general form of an operator function is: return type className :: operator op(arglist){     function body //task definded } where return type is the type of value returned by the spec...
