Which of the following cannot be checked in a switch-case statement?
[A]. Character [B]. Integer [C]. Float [D]. enum
Answer: E
Explanation:
The switch/case statement in the c language is defined by the language specification to use an int value, so you can not use a float value.
switch( expression )
{
case constant-expression1: statements 1;
case constant-expression2: statements 2;
case constant-expression3: statements3 ;
...
...
default : statements 4;
}
The value of the 'expression ' in a switch-case statement must be an integer, char, short, long. Float and double are not allowed.

Case value must be an int, char, enum but not double and float float is the answer for this question.

Switch case does not accept the float value.

Yes. Enum can be checked. As an integer value is used in enum.

The switch/case statement convert the float into an int and use it, so long as the resulting values and functionality meet your functional requirements.
