Implementation inheritance is like sharing your toys with your friend. Imagine you have a toy car and your friend wants to play with it too. You can share the car with him and both of you can have fun playing together.
Now, in programming, we also have something called classes that are like toys. Each class has its own methods and properties that make it different from others. When we use implementation inheritance, we share these methods and properties with another class, just like sharing toys with our friend.
So, if we have a class called Car and another class called Truck, we can make Truck inherit the methods and properties of Car so that they both have similar behaviors. Then, we can add some new methods and properties to Truck that make it unique and different from Car.
In this way, implementation inheritance helps us reuse some common functionalities of a class in another class, saving us time and effort in writing new code from scratch.
