C Tutorials switch statement Control Statements in C The switch expression is evaluated once The value of the expression is compared with the values of each case If there is a match, the associated block of code is executed The break statement breaks out of the switch block and stops the execution The default statement is optional, and specifies some code to run if there is no case match No, in C switch cases need to be constant integral numeric values (C Standard 6.8.4.2)

The C switch statement is a control flow structure that executes code blocks based on the value of an expression, allowing for cleaner handling of multiple conditions compared to if-else statements. The switch expression is evaluated once The value of the expression is compared with the values of each case If there is a match, the associated block of code is executed The break statement breaks out of the switch block and stops the execution The default statement is optional, and specifies some code to run if there is no case match

The switch expression is evaluated once The value of the expression is compared with the values of each case If there is a match, the associated block of code is executed The break statement breaks out of the switch block and stops the execution The default statement is optional, and specifies some code to run if there is no case match 在 C 语言中, switch 语句中的表达式必须是常量表达式,且必须是整型或者枚举类型,所以 switch 语句不能直接匹配字符串。 重点来了,既然 switch 语句能够匹配枚举类型,那么创建一个包含所有控制命令的枚举类型,上述问题就迎刃而解了。 To accommodate for strings in the switch statement, C has implemented the switch with string mechanism which allows a programmer to check for and run case statements with string conditions.

Examples of Switch Statements in C Made easy Lec 32.1. string, float, bool, vector, etc.) data-types are assigned to the switch's case: statements 但是在c++中,是不能用字符串来作为case的标签的;于是,很疑惑,我们只能用其他的办法来实现这样的需求。 但幸运的是, c++11 引入了constexpr和自定义文字常量,将这两个新特性结合,我们实现出看上去像上面这样的代码。

How to Use Strings in Switch Statement in C Delft Stack. Furthermore, its necessary that the values assigned to the case: statements are const. I don't see another way but to use strcmp or strncmp to do the string comparisons.
