How do you find the range of a switch statement?
In the switch statement we pass some value, and using different cases, we can check the value. Here we will see that we can use ranges in the case statement. After writing case, we have to put lower value, then one space, then three dots, then another space, and the higher value.

You all are familiar with switch case in C/C++, but did you know you can use range of numbers instead of a single number or character in case statement. case ‘A’ ‘Z’:
When to use switch statement with case values?
By this way, we do not need to use write values with separate cases, if the values that you want to validate are in range and want to execute the same body (set of statements), we can use switch statement with the case values in a range.
What is the condition of a switch statement?
The condition of a switch statement is a value. The case says that if it has the value of whatever is after that case then do whatever follows the colon. The break is used to break out of the case statements.
