//OK! Now, privateVariableOne = 21

}

In the above code stub, the following code represents the constructor -

ExampleClass(int publicVariableValue) {

//This is the constructor

publicVariableOne = publicVariableValue;

}

It takes in an integer and assigns its value to publicVariableOne.

To instantiate an object of the class where the value of publicVariableOne will be 30, we do the following:

ExampleClass object(30);

Now, there’s another way of instantiating values in the constructor: ExampleClass(int publicVariableValue):publicVariableOne(publicVariableValue) {

//This is the constructor

}

Example- Create a Dog class that stores a dog’s age and the name and has methods called bark and eat.

#include<iostream>

#include<string>

using namespace std;

class Dog {

private:

int age;

string name;

public:

Dog(int dogAge, string dogName) :age(dogAge), name(dogName) {}

void printDogName() {

cout << "Dog Name: " << name << endl;

}

void printDogAge() {

cout << "Dog Age: " << age << endl;

}

void bark() {

cout << "WOOOF WOOOOF!!" << endl;

}

void eat() {

cout << "I'm eating right now. Don't bother me!" << endl;

}

};

int main() {

Dog henryTheDog(2, "Henry");

henryTheDog.printDogName();

henryTheDog.printDogAge();

henryTheDog.bark();

henryTheDog.eat();

}

Here’s the output -

Dog Name: Henry

Dog Age: 2

WOOOF WOOOOF!!

I'm eating right now. Don't bother me!
