2 min 2 sec read

What is Switch Statement ?

The control statement that allows us to make a decision from the number of choices is called a switch, or more correctly a switch- case-default, since these three keywords go together to make up the control statement.

Generic Syntax of switch-case Statements :-

switch expression
   case expression1  :
      break;     /* optional */
   case expression2  :
      break;     /* optional */
   default : /* Optional */

switch statements can accepts \'integer constants\' or \'Character variables\'.

What happens during the execution of switch statements ?

Firstly , expression under switch keyword inside parenthesis is evaluated .Then each case is evaluated one by one unless and until match is found. If no match is found , default case is being executed.
