Web Reference: This is how it works: The switch expression is evaluated once. The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed. If there is no match, no code is executed. Jul 8, 2025 · Execution will continue at the first statement following switch. If break is omitted, execution will proceed to the next case clause, even to the default clause, regardless of whether the value of that clause's expression matches. This behavior is called "fall-through". This guide covers the switch statement thoroughly, explains exactly how fall-through works, shows you when switch is the right tool, and helps you avoid the most common mistakes.
