Encapsulation

class Bird { string name, color, gender; public: Bird(string n, string c, string g) { name = n; color = c; gender = g; }

};

int main() {

	Bird b("gauraiya", "brown", "female");
	return 0;
}

The above code has three problem:

1. Dirty code.
2. Client have to remember the sequence of parameter.
3. Backward compatibility.

Problems can be solved using Builder pattern.
