Switch case statements are controlled assertions that are seemed like an alternative for if-else statements. A switch statement in c++ is a multiway branch declaration that gives a way to prepare the float of execution to elements of code-based totally at the value of the expression. In a very primary time, a transfer declaration evaluates an expression, tests it, and compares it in opposition to the numerous cases written within the code. As soon as a suit with any case is determined, the manager will input that case and begin executing the statements written in that case till a break assertion has been observed. As soon as a wreck statement seems, the transfer statement terminates, and this system control exits the switch.

It might once in a while show up that no case fits up with the cost of the expression. For such cases, we mention a default case to continually execute in case no fit is observed. The instances in a block of a switch announcement are represented via distinct numbers or strings, which is called an identifier. The cost of the expression or the price furnished with the aid of the user is compared with these cases until the in shape is located.

The syntax for switch statement in C++ programming language is given below-

You need to keep the following things in mind when using a Switch Statement :

Case labels can be an integer or a character, and they should be unique

Even though a default case label is not mandatory, it can at most be one if defined.

You need a break statement to take the control out of the loop; otherwise, all the cases before a break would be executed.

The default case label does not have any specific position.

Lets us see some of the examples of the switch statement in C++.

This example will give more clarity about the use of switch statements.

cout << "Outstanding Result!\n"  << endl;

cout << "You did not appear for exam\n"  << endl;

This example depicts the use of the break statement in a switch. If the break statement is not specified after the case, the execution flow will continue until it encounters the break statement.

cout << "The number is 10 or 20 or 30 " << endl;

case 55:cout << "This case also executes because there is no break " << endl;

cout << "The number is either 40 or 50 or 60" << endl;

cout << "The number is greater than 60" << endl; }}

In this blog, we will discuss Switch Statement in C++

Uses of Switch Statement in C++

The switch statement in C is an alternative to the if-else-if ladder statement which allows us to execute multiple operations for the different possible values of a single variable called the switch variable. Here, we can define various statements in multiple cases for the different values of a single variable.

 code to be executed if all cases are not matched;    

Allow us to comprehend the progression of control portrayed in the flowchart above to acquire a superior comprehension of the progression of execution.

An articulation is passed with the switch statement, which is equivalent to one of the upsides of the cases. On the off chance that the worth isn't equivalent, the default case is executed. The worth of this articulation is then contrasted and the case identifier or the main case. If the principal case matches, then, at that point, the square of code related to the main case is executed. When the break is experienced, the execution stops, and you will leave the switch statement. In any case, if the case doesn't coordinate, the execution streams to the following case. If this case matches, then, at that point, the subsequent code block executes; in any case, the stream looks at the following case along these lines. At last, if no case matches, then, at that point, the default code block is executed.

This model portrays the utilization of the break statement in the switch. If the break statement isn't specified after the situation, the execution stream will go on until it experiences the break statement.

case 55:printf("This case also executes because there is no break ");

printf("The number is either 40 or 50 or 60");

printf("The number is greater than 60");}}

It is our goal in this blog post to introduce you to the switch statement in C,in which we will learn how it works,its flowchart,and examples of how it can be used.
