Find the output for the following.

public class IncDec

{

public static void main(String s[])

{

int a = 1;

int b = 2;

int c;

int d;

c = ++b;

d = a++;

c++;

System.out.println("a = " + a);

System.out.print("b = " + b);

System.out.println("c = " + c);

System.out.print("d = " + d);

}

}

• a = 2 b = 3 c = 4 d = 1

• a = 2 b = 3 c = 4 d = 1

• Program does not compile.

• a = 1 b = 2 c = 4 d = 2
