Which of the following cannot be checked in a switch-case statement?
Answer: Option
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.

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.
