Polymorphism in C++ Operator Overloading ppt download

Operator Overloading Operator Overloading allows a programmer to define new types from the built-in types. Operator Overloading is useful for redefining built-in operations for user defined types. Operator Overloading should be used to perform the same function or similar function on class objects as the built-in behavior. Overloading an operator does not change: the operator precedence, the associativity of the operator, the arity(type) of the operator, or the meaning of how the operator works on objects of built- in types
int main() { PhoneNumber phone; // create object phone. cout << Enter phone number in the form (123) :\n ; // cin >> phone invokes operator>> by implicitly issuing. // the non-member function call operator>>( cin, phone ) cin >> phone; cout << The phone number entered was: ; // cout << phone invokes operator<< by implicitly issuing. // the non-member function call operator<<( cout, phone ) cout << phone << endl; return 0; } // end main. Enter phone number in the form (123) : (800) The phone number entered was: (800)
