• To reverse a string without using built-in functions, use two pointers approach.

• Example for swapping numbers: a = a ^ b; b = a ^ b; a = a ^ b;

• Inheritance: Mechanism to create a new class using properties of an existing class. Example: class ElectricCar extends Car {...}

• Polymorphism: Ability to p...read more
