What will be the output of the following C++ code?
#include <iostream>
using namespace std;
class Player
{
private:
int id;
static int next_id;
public:
int getID() { return id; }
Player() { id = next_id++; }
};
int Player::next_id = 1;
int main()
{
Player p1;
Player p2;
Player p3;
cout << p1.getID() << ” “;
cout << p2.getID() << ” “;
cout << p3.getID();
return 0;
}
a) 1 2 3
b) 2 2 2
c) 1 3 1
d) 1 1 1

Answer: a
Explanation: In this as next_id is a static variable so and initialized with 1 therefore the id value for 1st objects is 1 and next_id is updated to 2. In this way next_id is assigned to id in each object creation and updated by 1 so in this way value of each Id is updated.
