A constructor in C++ is a special method that is automatically called when an object of a class is created.
To create a constructor, use the same name as the class, followed by parentheses ():
Example
class MyClass { // The class
public: // Access specifier
MyClass() { // Constructor
cout << "Hello World!";
}
};
int main() {
MyClass myObj; // Create an object of MyClass (this will call the constructor)
return 0;
}
public: // Access specifier
MyClass() { // Constructor
cout << "Hello World!";
}
};
int main() {
MyClass myObj; // Create an object of MyClass (this will call the constructor)
return 0;
}
Note: The constructor has the same name as the class, it is always
public, and it does not have any return value. Practice Excercise Practice now
