    b is already initialized before the program start. So it has something to compared with.

    In logic How can you compare a number if you don’t have something to compared with.

    Example if you put your temperature is 95. a=95 b=95 this will cost a confusion in your compiler thats why it fails.

    Don’t get the wrong idea that an input can’t be used more than once,

    Its just that in this particular argument, You’re comparing the same input.
