![]() ![]() If the value of a test expression is not true for any case, the default case is executed. ![]() The default case is optional and appears at the end of the switch. ![]() If the ‘break’ is not added in a case, the flow of control will not terminate and continue to execute all the cases. The flow of control now jumps to the next line of the switch statement. The ‘Break’ keyword marks the end of a certain case. If the case label being switched on is equivalent to the variable, the case statements execute until a break statement is reached. ![]() This can change the output of the entire program and fail to produce the desired result. When executing the program, the label that appears first will be executed first even if you want to execute a second case. For example, two cases have been labeled X. Be sure that none of the case labels is the same and each is named according to the preference of execution. The value A, B, and n are case labels that are used for identifying each case individually. Each case is then followed by different case labels that always end with a colon (:). There can be multiple case statements within a switch called a block. The switch variable or expression can be defined as an integral/enumerated or class type. With reference to this, let’s learn the working of a switch case statement. The variables are evaluated and compared with several integral values. Given here is the syntax of the switch statement. Part 2: Syntax and Working of Switch Statement Switch statements work similarly to the ‘if’ statement used in high-level programming languages.įlowchart is a formalized graphic representation of a logic sequence, workflow or manufacturing process, or similar formalized structure. It allows testing a variable against a list of values to change the control flow of program execution via a search and map. There are two main variants of switch statements, the first one is a structured switch, which takes exactly one branch, and the second one is an unstructured switch which functions as a type of goto. It is easy to understand, read, maintain and verify that all values are handled. Switch statement is one of computer programming languages, which means a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution via a multiway branch. Creating flowchart for switch statement is a good way for software engineers to improve clarity and offer the potential for faster execution. ![]()
