int c = 20; switch ( a ) { case b: /* Code */ break; case c: /* Code */ break; default: /* Code */ break; }The default case is optional, but it is wise to include it as it handles any unexpected cases. It can be useful to put some kind of output to alert you to ...
The procedure of this article explains the concept of the switch case in the C language. We follow the sequential procedure where we first learn about the syntax of the switch case. Then, we try to practically solve some examples for the various problems of switch cases. Syntax Switch(express...
Multiple Cases in One Block (Fall-Through) When the parameter inputValue is set to 'C'. public void UseOfMultipleSwitchCase(char inputValue) { switch (inputValue) { case 'A': case 'B': case 'C': Console.WriteLine("You passed!"); break; case 'D': case 'F': Console.WriteLine("...
By this way, we do not need to use write values with separate cases, if the values that you want to validate are in range and want to execute the same body (set of statements), we can use switch statement with the case values in a range....
This is two-way condition in C –‘if-else’ condition. If programmer wants to execute one set of statements on success case of one condition and another set of statements in all other cases, then ‘if-else’ condition is used. Either ‘if’ case statements are executed or ‘else’ case...
This is because C falls through the subsequent case blocks in the absence ofbreakstatements at the end of the blocks. Example 3: Grade Checker Program using Switch Statement In the following program, "grade" is the switching variable. For different cases of grades, the corresponding result messa...
default:// code to be executed if n doesn't match any cases } 一些重要的关键词: 1) Break:此关键字用于停止 switch 块内的执行。它有助于终止开关块并打破它。 2) 默认值:该关键字用于指定在没有大小写匹配时执行的语句集。 注意:有时当 switch case 程序的末尾没有放 default 时,我们应该在 defa...
Here,switch (wikitechy) will call the "wikitechy" in the code, which we have specified as "1". We have theswitch-cases as case "1", case "2" and case "3" which executes based on the function call for that wikitechy. If these cases fail it will execute the default case statement...
This terminates the switch statement. If the break statement is not used, all cases after the correct case are executed. You can visit the article on C++ Program to Make a Simple Calculator to learn more.Before we wrap up, let’s put your knowledge of C++ switch..case Statement to the ...
theswitch-caseStatement in C++ Theswitch-caseevaluates the expression, based on its value, and is tested against a list of constant values present incasestatements to perform different actions based on differentcases. Likeif-else, switch statements are control flow statements because they can alter ...
