 also told me about it,,,, Q no 1 is true and false

  1. var  = 28 * 13+2

There is no space before and after the plus operator.

  1. var  = 28 * 13 + 2

that’s true

  1. This.is.null.string = NULL
  2. There is no need to mention NULL,

But is true.

This.is.null.string =

Now the string is also have a null value.


  1. MONTH = ‘MAY’


  2. SEAT  = ROWNO + 6 /2

There should be space after the division operator.

SEAT  = ROWNO + 6 / 2 true now
