the case label that contains the matching value. If there is no matching value but there is a default label in the switch body, control passes to the default labelled statement. If no matching value is found, and there is no default label anywhere in the switch body, no part of the switch body is processed

How can you write a Algorithm using switch case in C language with examples?
A switch is a selection statement. We don't use switch statements to create algorithms, although they can form part of an algorithm. The controlling expression must evaluate to a value of integral type or an enum. We can then define case labels for some or all possible evaluations of the control expression. If required, we can define a default label to catch any and all values not explicitly labelled. Upon evaluating the expression, if there is no corresponding case label, control passes to the next statement after the switch statement. Otherwise, control immediately passes to the corresponding case label and execution continues from there until a break, return or goto statement is encountered. If there is no break, return or goto statement before the next case label is encountered, execution "falls through" to the next case. When using fall through, the order of labels is important. Notably, the default label (if any) need not be the final label.
What is a label in c plus plus?
A label is simply a user-defined name that appears on its own line and is followed by a colon. Labels are used with goto statements. Labels are also used with switch statements, where each case label is an unique label that represents the result of the expression evaluated by the switch statement. Labels are ignored by the code that immediately precedes them, they are only used to mark the address of the code that immediately follows.

What is the syntax and purpose of the switch statement in c plus plus?
The purpose of a switch statement is to execute one of several sections of code, depending on the value of an integral expression. The syntax of a switch statement can be stated as follows: switch(expression) { case(constant_expression_1): statement case(constant_expression_2): statement //.. case(constant_expression_n): statement [default: statement] } The ellipses around the constant expressions are optional and may be omitted. The switch statement body consists of one or more case labels and an optional default label (the case labels are also optional, but a switch statement would be meaningless without them). The default statement, if present, need not be the final label in a switch statement. Case and default labels may not appear outside of a switch statement, as they are not treated the same as goto labels. The constant_expression in each case label is converted to the type of the switch expression and is compared with the switch expression for equality. Control is immediately passed to the labelled statement whose constant_expression matches the value of the switch expression. Once a label gains control, execution proceeds from that point on and is not impeded by any subsequent case or default labels. However, a break statement may be used to interrupt execution at any time, which will transfer control to the statement immediately following the switch statement body. You may also use a return statement to return control to the calling function, or a goto statement. However, note that while a goto label is not the same as a case label, you may use goto labels inside a switch statement if required. Here's an example demonstrating how code flows through a switch statement: int x; switch(x=rand()%10) // x is a random number in the range 0 to 9. { case(0): x=42; break; case(1): case(2): x=33; break; case(3): x=100; default: x=0; } If x were 0, then execution passes to case(0) where the value 42 is assigned to x and the switch exits. If x were 1 or 2, then 33 is assigned to x and the switch exits. If x were 3, 100 is assigned to x. In all other cases, 0 is assigned to x. You will note that when the switch statement ends, x can only ever be 42, 33 or 0. Why not 100? Look again and you will see that case(3) has no break statement (just as case(1) has no break statement). So although 100 is assigned to x in case(3), the default case immediately assigns 0 to x. This is not a particularly useful switch statement, but it serves to demonstrate how code flows through a switch statement, and how forgetting to put a break statement at the end of a case can cause unexpected errors to creep into your code. While you could emulate the same results using a series of if, else if and else statements, the benefit of a switch statement is that it will generally simplify the complexity of your code, because there is only one expression to evaluate, rather than a series of boolean expressions. Your compiler will generate machine code just as if you'd used a series of if statements, but the switch statement gives a greater sense of structure to the statement, and gives a greater degree of control over which section(s) of code will execute for any given evaluation. And just as ifs can be nested within other ifs, switch statements can be nested within other switch statements. Note that all code in a switch statement must be reachable (that is, not bypassed by all execution paths). For instance the following contains both unreachable and undefined code: switch(x) { x=42; //unreachable case(100): int y=42; break; default: x=y; // y is undefined } The line x=42 cannot be reached because execution must either pass to either the case(100) or the default label. Similarly, the x=y line is invalid because y is defined within the case(100) label, which is not reachable from within the default label due to the break statement.

Why break statement is optional in c plus plus?
You use a break statement to end execution of the enclosing iterator (loop) or switch statement. If omitted at the end of a case label, execution continues to the next case label, including the default case, until a jump statement is encountered (break, goto or return) or the switch statement falls from scope. Sometimes this can be desirable behaviour, thus the use of break is optional. A break statement is always optional at the end of the default case, or the last case label. Its usage in loops is always optional, to allow a loop to end prematurely regardless of the conditional expression that controls the loop.
