1. switch case语句的基本语法 在C语言中,switch case语句的基本语法如下所示: ``` switch (expression) { case constant1: // statements break; case constant2: // statements break; ... default: // default statements break; } ``` - `switch`关键字用于指定一个表达式,该表达式的值将被用来进行匹...
switch语句的语法如下（switch，case和default是关键字）：switch （ controllingExpression ）{ case constantExpression1 ：case constantExpression2 ：case constantExpression3 ：statements； //当满足constantExpression1、constantExpression2、constantExpression3任何一个都执行statements break；case constantExpr...
在C语言中,case语句通常与switch语句一起使用。switch语句用于多种条件下的选择,而case语句用于定义每个条件下的操作。 switch语句的基本语法如下: switch(expression) { case constant1: // statements break; case constant2: // statements break; case constant3: // statements break; default: // statements ...
switch case 语句的基本结构如下: ``` switch (expression) { case constant1: // code to be executed if expression is equal to constant1; break; case constant2: // code to be executed if expression is equal toconstant2; break; // you can have any number of case statements case constant...
C编程语言中switch语句的语法如下 - switch(expression) { case constant-expression : statement(s); break; /* optional */ case constant-expression : statement(s); break; /* optional */ /* you can have any number of case statements */ default : /* Optional */ statement(s); } 1 2 ...
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...
switch( c ) {case'A': capital_a++;case'a': letter_a++;default: total++; } All three statements of theswitchbody in this example are executed ifcis equal to'A', since nobreakstatement appears before the followingcase. Execution control is transferred to the first statement (capital_a++;...
switch( c ) { case 'A': capital_a++; case 'a': letter_a++; default : total++; } All three statements of the switch body in this example are executed if c is equal to 'A', since no break statement appears before the following case. Execution control is transferred to the first ...

statements executed if expression does not equal any case constant-expression } 可以使用break语句结束 switch 语句中特定用例的处理并分支到 switch 语句的末尾。 如果不使用break,则程序会继续到下一用例,并执行语句,直到达到break或该语句的末尾。 在某些情况下,可能需要此继续符。
