Practice Quiz on Reading and Understanding Code

  1. What value would be printed for the following code? 
        int val = 12 - 4 / 2;
    System.out.println(val);


  2. Read the following loop. How many question marks will it print? 
        for ( int i = 10; i > 5; i-- )
    {
        System.out.println("?");
    }





  3. Read the following loop. How many question marks will it print? Tip: Trace or "mind-execute" the code, keeping track of the values of i and j as you go. 
        for ( int i = 0; i < 5; i++ )
    {
        for ( int j = i; j < 3; j++ )
        {
            System.out.println("?");
        }
    }
