Q-1) What will be the output of the following program?     
        int i = 4;
        int j = 21;

        int k = ++i * 7 + 2
        System.out.println("k = " + k);
        
    A) K=37
    B) Program does not compile

    B) 27
    C) 35
    Answer: C) 27
Q-3) What will be the output of the following program?     
        int i, j, k, l = 0;
        k = l++;
        j = ++k;
        i = j++;
        System.out.println(i);
        
    A) 0
    B) 1
    B) 2

Q-4) What will be the output of the following program?     
        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)  a = 2
     b = 3c = 4
     d = 1
  
 B)  a = 2
     b = 3
     c = 4
     d = 1
     
 C) Program does not compile.

 D) a = 1
    b = 2
    c = 4
    d = 2
    Answer: A)  a = 2
                b = 3c = 4
                d = 1
