Break Statement
The break statement is an important element within the switch block. After a matching case is executed, the break statement terminates the switch block entirely, preventing the program from accidentally falling through and executing code from subsequent cases. This is also called fallthrough behaviour.
Here’s an example to illustrate this.
// This is just a pseudo-code switch (day) { case 1: print("Monday"); break; case 2: print("Tuesday"); // Without a break here, Wednesday will also be printed if day is 2! case 3: print("Wednesday"); break; // ... more cases }
In this example, if day is 2, both “Tuesday” and “Wednesday” will be printed without the break statements.
Switch statement in Programming
Switch statement in programming enables the execution of different code blocks based on the value of an expression, providing a structured approach to handle multiple cases efficiently. It enhances code readability and simplifies decision-making processes, making it a valuable tool for managing program flow and facilitating branching logic in software development.
