When match of  integer or character is found then the statement associated with that constant is execueted .

{
case 1: statement associated with 1;
break;

case 2: statement associated with 2;
break;

case 3: statement associated with 3;
break;
default: default statement;
break;
}


Explanation: switch () will check for the the match of the condition , and will execute the statement associated with matching case . The statement will be executed till it encounters Break statement.
If there is no break statement execution will continue to next case till it encounter break statement or en of switch statement.

Default statement get executed when no matching case is found. it is an optional statement. If default statement is missing and all matches fail then no action will take place
