The entry expression is optional in switch, the default value is True (if nothing is mentioned). There is no break statement in Golang's switch statement, the code breaks by default after each case. The programmer can explicitly use the break and fall through statements for cases if required...
If there is a match, the corresponding code after the matching label is executed. For example, if the value of thevariableis equal toconstant2, the code aftercase constant2:is executed until thebreak statementis encountered. If there is no match, the code afterdefault:is executed. Note: We...
Control is transferred to the statement after the switch statement.If a matching expression is found, execution can continue through later case or default labels. The break statement is used to stop execution and transfer control to the statement after the switch statement. Without a break statement...
If no match is found and a default statement exists, the default statement executes. Make sure to use a break statement to end each case. In the following example, if the break statement after the "I=I+2;" statement were omitted, the computer executes both "I=I+2;" and "I=I+3;"...
每个对象都有SwitchCase一个隐式break语句,这意味着不存在从一个事例标签到另一个事例标签的隐式下降。 如果switchValue与任何事例不匹配,则运行 由defaultBody表示的默认事例。 适用于 .NET 9 和其他版本 产品版本 .NETCore 1.0, Core 1.1, Core 2.0, Core 2.1, Core 2.2, Core 3.0, Core 3.1, 5, 6, 7...
) default: fmt.Println("It's the weekend, time to rest!") } fmt.Println(time.Now().Weekday().String()) } When you call a function from a switch statement, you can modify its logic without changing the expression because you always validate what the function returns....
We can easily guess that the use of abreakstatement inside thedefaultlabel is not necessary because thedefaultlabel is the last label in theswitchstatement and the execution of theswitchstatement will stop after that anyway. 1.3. Demo In this example, we are checking if today is a weekend or...
switch( i ) { case -1: n++; break; case 0 : z++; break; case 1 : p++; break; } In this example, a break statement follows each statement of the switch body. The break statement forces an exit from the statement body after one statement is executed. If i is equal to -1, on...
Expression.Lambda<Action>(switchExpr).Compile()(); // This code example produces the following output: // // Default 注解 SwitchCase对象中的所有SwitchExpression对象必须具有相同的类型,除非 SwitchExpression 的类型为 void。 每个对象都有 SwitchCase 一个隐式 break 语句,这意味着不存在从一个事例标签...
