statement(s); } expression:表达式,可以是变量或者任何类型的表达式。 value:case子句中的常量表达式,必须与switch中的表达式的值匹配。 statement:当表达式的值与case子句的值相等时,要执行的语句。 break:用于终止switch语句,终止switch语句后,程序将继续执行紧接着switch语句后面的语句。 default:当表达式的值与case...

在C语言中，case是switch语句的一个关键字，用于指定多个分支条件。switch语句用于根据不同的条件执行不同的代码块，其基本语法如下：switch(expression) { case constant-expression: statement(s); break; case constant-expression: ...
statement1statementN是与每个case关键字相关的语句序列，表示在对应值匹配时要执行的一系列语句。default是可选的，表示如果表达式的值与所有case关键字的值都不匹配，则执行的语句序列。当程序执行到switch语句时，首先计算表达式的值。然后，将表达式的值与每个case关键字的值进行比较，直到找到匹配的值或执行了default...

Switch case statement is used when we have multiple conditions and we need to perform different action based on the condition. When we have multiple conditions and we need to execute a block of statements when a particular condition is satisfied. In such
switch(variable) { case value: //code case value: //code default: //code } The braces are always needed following the switch statement. No braces are needed following any case. If the variable is equal to one of the values following a case, then the code following the case is executed...
