How do you use a switch-case inside switch-case?

How do you use a switch-case inside switch-case?

Points to remember while using Switch Case There can be any number of case statements within a switch. Each case is followed by the value to be compared to and after that a colon. When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached.

How do you apply or condition in a switch-case?

Here the mark is defined as 100 and when switch statement is executed, the condition will be checked as follows.

1. case mark <=35. true => (100 <= 35) – this will give the result false.
2. case mark >=36 && mark <= 60. true === (100 >=36 && 100 <= 60)
3. case mark >= 61 && mark <= 80.
4. case mark >= 81.

How does a switch-case work?

A switch works with the byte , short , char , and int primitive data types. A statement in the switch block can be labeled with one or more case or default labels. The switch statement evaluates its expression, then executes all statements that follow the matching case label.

Can I use or in switch-case?

The switch-case construct is pretty similar to an if-else statement, you can use the OR operator in an if however.

When would you use a switch-case?

Use switch every time you have more than 2 conditions on a single variable, take weekdays for example, if you have a different action for every weekday you should use a switch. Other situations (multiple variables or complex if clauses you should Ifs, but there isn’t a rule on where to use each.

How do you write a switch case in an algorithm?

A general syntax of how switch-case is implemented in a ‘C’ program is as follows: switch( expression ) { case value-1: Block-1; Break; case value-2: Block-2; Break; case value-n: Block-n; Break; default: Block-1; Break; } Statement-x; The expression can be integer expression or a character expression.

What happens if no break in switch case?

It branches to the end of the switch statement. Without break , the program continues to the next labeled statement, executing the statements until a break or the end of the statement is reached. If there’s no default statement, and no case match is found, none of the statements in the switch body get executed.

How many case statments can I use in switch statement?

You can have any number of case statements within a switch. Each case is followed by the value to be compared to and a colon. The constant-expression for a case must be the same data type as the variable in the switch, and it must be a constant or a literal.

What is a case in a switch statement?

Switch case statements are a substitute for long if statements that compare a variable to several “integral” values (“integral” values are simply values that can be expressed as an integer, such as the value of a char). The basic format for using switch case is outlined below.

What is a switch case?

A switch case is used test variable equality for a list of values, where each value is a case. When the variable is equal to one of the cases, the statements following the case are executed. A break statement ends the switch case. The optional default case is for when the variable does not equal any of the cases.

What is a switch case in C?

Summary A switch is a decision making construct in ‘C.’ A switch is used in a program where multiple decisions are involved. A switch must contain an executable test-expression. Each case must include a break keyword. Case label must be constants and unique. The default is optional. Multiple switch statements can be nested within one another.
