If you do not want to browse programs by categories, here is the list of all c programs. Comments and Discussions. Are you a blogger? Join our Blogging forum.

A switch construct is used to compare the value stored in variable num and execute the block of statements associated with the matched case. In this program, since the value stored in variable num is eight, a switch will execute the case whose case-label is 8. After executing the case, the control will fall out of the switch and program will be terminated with the successful result by printing the value on the output screen. Try changing the value of variable num and notice the change in the output.

You need to introduce a break statement in each case to branch at the end of a switch statement. The optional default case runs when no other matches are made. Nested Switch In C, we can have an inner switch embedded in an outer switch.

Also, the case constants of the inner and outer switch may have common values and without any conflicts. Otherwise, the switch case will trigger the default case and print the appropriate text regarding the program outline.

Why do we need a Switch case? There is one potential problem with the if-else statement which is the complexity of the program increases whenever the number of alternative path increases. If you use multiple if-else constructs in the program, a program might become difficult to read and comprehend. Sometimes it may even confuse the developer who himself wrote the program. The solution to this problem is the 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.

Switch Case Statement in C Programming with Example

Summary A switch is a decision making construct in 'C. A switch must contain an executable test-expression. Each case must include a break keyword. The birth of oops concept took place with encapsulation. Any program contains two parts. Date part and Logic part Out of data and logic the highest priority we have given to data. But in a structured programming language, the data insecurity is high. Thus in a process, if securing data in structured prog.

Note: In structured programming lang programs, the global variable play a vital role. But because of these global variables, there is data insecurity in the structured programming lang programs. In this way data is unsecured.

But this is not the actual reason. Assume that it is a project.

Now if any upgradation is required, then the client i. Now we should note that it is not guaranteed that the programmers who developed this program will still be working with that company. Hence this project falls into the hands of new programmers. Automatically it takes a lot of time to study. The project itself before upgrading it.
