Use the switch statement to select one of many code blocks to be executed. This is how it works: The example below uses the weekday number to calculate the weekday name: When C++ reaches a break keyword, it breaks out of the switch block.

The `switch` statement in C++ allows you to execute different blocks of code based on the value of a variable, making it a cleaner alternative to multiple `if-else` statements.
The switch statement allows us to execute a block of code among many alternatives. You can do the same thing with the if...else statement. However, the syntax of the switch statement is much easier to read and write. Syntax. case constant1: // code to be executed if // expression is equal to constant1; break; case constant2:
