C++ Switch

C++ Switch Statements

Use the switch statement to select one of many code blocks to be executed.

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.
• The break statement breaks out of the switch block and stops the execution.
• The default statement executes if there is no match.

Switch statements are often more efficient and readable than long chains of if..else if statements.
