Standard C specifies that a switch can have at least 257 case statements. Standard C++ recommends that at least 16,384 case statements be supported! The real value must be implementation dependent.
.
Also know, how many cases can a switch statement have in Java?
3 case statements
Secondly, can cases in switch statement have conditions? A statement in the switch block can be labeled with one or more case or default labels. An if-then-else statement can test expressions based on ranges of values or conditions, whereas a switch statement tests expressions based only on a single integer, enumerated value, or String object.
Similarly, you may ask, what are the rules for switch statement?
Rules for switch statement:
- An expression must always execute to a result.
- Case labels must be constants and unique.
- Case labels must end with a colon ( : ).
- A break keyword must be present in each case.
- There can be only one default label.
- We can nest multiple switch statements.
What are the limitations of if and switch statements?
Disadvantages of switch statements
- float constant cannot be used in the switch as well as in the case.
- You can not use the variable expression in case.
- You cannot use the same constant in two different cases.
- We cannot use the relational expression in case.

What is the Do While loop syntax?
Syntax. do { statement(s); } while( condition ); Notice that the conditional expression appears at the end of the loop, so the statement(s) in the loop executes once before the condition is tested. If the condition is true, the flow of control jumps back up to do, and the statement(s) in the loop executes again.
What is switch in C?
Switch Statement in C/C++ Switch case statements are a substitute for long if statements that compare a variable to several integral values. The switch statement is a multiway branch statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression.
