The data types allowed in the test expression of a switch statement are int, char and enum, use of any other data type is not allowed.
The case expression of can have only constant values and it must also be noted that two case expressions cannot have same value. i.e 2 and 1+1 are same and they cannot be used in two different cases inside a switch.
Why floats and doubles are not allowed in the test expression of a switch statement, for this you must note that a switch statement requires a exact value, but floats like (1.2) are stored in the memory as approximations that is they are not exact, due to the limitation of the binary number system.
Hope it answers your question :)
