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
What will be the output of the program?

System.out.println(sup);
}
}
