switch,case,default statement tutorials

  • The switch statement is a multi-way decision-making construct that tests wheather an expression matches one of a number of constant values and branches accordingly.

  • The switch statement is a neater alternative to using else-if statements where multi-way decision making is involved.

  • The expression must be enclosed in parentheses, and the body of the switch statement must be enclosed in braces.

  • Statements can be single or multiple statements with or without braces.

  • The values with case should be constants.The expression is evaluted and the resultant value is compared with each of the values given with case.

  • If any of the values match,the statements following the case, till break, are executed.

  • If none of the case values match the result of expression , then the statements following default,which is optional, are executed.

  • The keyword break is used to delimit the scope of the statemants under a particular case.

 

Syntax:

switch(expression)

{

case value 1:

statements ;

break ;

case value 2:

statements ;

break ;

default :

statements ;

}
