Question

which of the following types of variable cannot be checked in switch case statement
1char 2int 3float 4enum​

Answer 1

Answer:

Option 3

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.
