Switch case statement is used when we have multiple conditions and we need to perform different action based on the condition. When we have multiple conditions and we need to execute a block of statements when a particular condition is satisfied. In such case either we can use lengthy if.else-if statement or switch case. The problem with lengthy if.else-if is that it becomes complex when we have several conditions. The switch case is a clean and efficient method of handling such scenarios.
The syntax of Switch case statement:
Switch Case statement is mostly used with break statement even though the break statement is optional. We will first see an example without break statement and then we will discuss switch case with break
- Mar 19, 2020 Selection is based upon the comparison of the value passed inside the switch block with those values which are already present inside the switch block. If no value matches, the default statement inside the switch block is executed. 2 – Loops: Basically we have three types of loops in C.

- Pada bahasa pemrogramana C kita dimungkinkan untuk mendirikan tapi tidak dapat inisialisasi. Mungkin ini terdengar normal karena kita juga bisa mendirikan variabel pada pernyataan penyeleksian if. Bukan hal itu yang akan penulis beritahu, ada sesuatu yang unik pada pernyatan switch.
Example of Switch Case
C: Switch Statements Sometimes when creating a C program, you run into a situation in which you want to compare one thing to a number of other things. Let's say, for example, that you took a character from the user and wanted to compare this to a number of characters to perform different actions. Oct 27, 2008 Nvm, I found that switch case statements only handle int and char values.
Output:
Explanation: In switch I gave an expression, you can give variable as well. I gave the expression num+2, where num value is 5 and after addition the expression resulted 7. Since there is no case defined with value 4 the default case got executed.

It evaluates the value of expression or variable (based on whatever is given inside switch braces), then based on the outcome it executes the corresponding case.
Break statement in Switch Case
Before we discuss about break statement, Let’s see what happens when we don’t use break statement in switch case. See the example below: https://celestialmakers.weebly.com/graillon-2-free-auto-tune-vst-plugin-by-auburn-sounds.html.
Output:
In the above program, we have the variable i inside switch braces, which means whatever the value of variable i is, the corresponding case block gets executed. We have passed integer value 2 to the switch, so the control switched to the case 2, however we don’t have break statement after the case 2 that caused the flow to continue to the subsequent cases till the end. However this is not what we wanted, we wanted to execute the right case block and ignore rest blocks. The solution to this issue is to use the break statement in after every case block.
Break statements are used when you want your program-flow to come out of the switch body. Whenever a break statement is encountered in the switch body, the execution flow would directly come out of the switch, ignoring rest of the cases. This is why you must end each case block with the break statement.
Let’s take the same example but this time with break statement.
Output:
Now you can see that only case 2 got executed, rest of the subsequent cases were ignored.
Why didn’t I use break statement after default?
The control would itself come out of the switch after default so I didn’t use break statement after it, however if you want you can use it, there is no harm in doing that.

Important Notes
1) Case doesn’t always need to have order 1, 2, 3 and so on. It can have any integer value after case keyword. Also, case doesn’t need to be in an ascending order always, you can specify them in any order based on the requirement.
2) You can also use characters in switch case. for example –

The switch statement in C++ is a control statement that is useful in a limited number of cases. The switch statement resembles a compound if statement by including a number of different possibilities rather than a single test:
https://celestialmakers.weebly.com/cooking-joy-super-cooking-game-download.html. The value of expression must be an integer (int, long, or char). The case values must be constants.
As of the ‘14 standard, they can also be a constant expression.
When the switch statement is encountered, the expression is evaluated and compared to the various case constants. Control branches to the case that matches. If none of the cases match, control passes to the default clause.
Consider the following example code snippet:

Once again, the switch statement has an equivalent; in this case, multiple if statements. However, when there are more than two or three cases, the switch structure is easier to understand.

The break statements are necessary to exit the switch command. Without the break statements, control falls through from one case to the next. (Look out below!)
