int main() {

PhonePlan user1Plan;

PhonePlan user2Plan(1000, 5000);

cout << "User1: ";

user1Plan.Print();

}

Explanation:

The C++ source code has a defined class called "PhonePlan" with a default constructor which initializes the phone time and messages of a user to zero and another constructor method which assigns the "numMessages" and "numMinutes" to the user messages and minutes and displays it in the console.
