Switch case statements are an efficient way to execute different blocks of code based on various conditions. It's like a more structured and readable if-else.
Basic Syntax
rreee
How It Works
- Expression is evaluated once.
- The value of the expression is compared for each case.
- If there is a match, the code block in that case is executed.
- Break is used to stop execution after finding a match.
- Default is optional and will be executed if no case matches.
Practical Example
Suppose we want to provide different messages based on the value of a variable day:
rreee
Tips
- Use switch case when there are many conditions that need to be checked.
- Don't forget to add a break to prevent execution from continuing to the next case.
- Default is useful for handling unexpected values.
Switch case makes the code cleaner and easier to understand compared to long if-elses. Try it in your projects and see the difference!
