If you want to execute only that case whose constant value equals the value of the expression of the switch statement, then use the break statement. Decision Making in programming is similar to decision making in real life. If omitted, execution will continue on into the next case. Given the ambiguity that exists around the use of switch-case in most languages, when using it I would suggest always using a break statement, except when it is explicitly and by design not wanted.. However nested switch statements should be avoided as it makes program more complex and less readable. If you omit the break statement, control falls through to the next case group.
