...具体来讲,while循环所作的和if语句类似,也是去检查一个布尔表达式的真假,不一样的是它下面的代码片段不是只被执行一次,而是执行完后再调回到while所在的位置,如此重复进行,直到while表达式为False...但是另一方面,for循环只能对某种事物的集合做循环,而while可以进行任何种类的循环。但是,while循环很容易出错,大...
Second, the reason your loop isn't working is because you redefine G on each iteration. You need to index into the iith element of G forii = 1:n iftheta(ii)==0 G(ii) = 0.5 else G(ii) = stuff_with(theta(ii)) end end ...
The loop terminates if the condition is false. Any expression that evaluates to a Boolean value can be the loop condition. Increment/Decrement: This statement/ expression is executed after every iteration of the loop. It defines how to modify the loop control variable and is hence called the ...
We used the For Next loop to iterate through the rows of data from the 5th row to the LastRow. We used the IF statement, to check if the value of the current cell in Column C is equal to 12. If the condition in the IF statement is True, the cell color will change. We used th...
LOOP 语句是特殊类型的循环语句,原因是它没有终止条件子句。它会定义重复执行的一系列语句直到另一块逻辑(通常是控制转移语句)强制控制流跳至循环外部某点。 LOOP 语句通常与下列其中一个语句配合使用:LEAVE、GOTO、ITERATE 或 RETURN。这些语句可强制控制权跳至 SQL 过程中紧跟循环之后的指定位置、跳至循环的开头以...

这将使break语句找不到正确的循环体，从而引发错误：break statement not within loop or switch。这是因为break语句只能在for循环或其他控制结构中使用，而在没有正确嵌套的循环中，break将无法找到有效的循环体。初始化表达式通常用于给循环变量赋值，例如初始化为0。条件表达式是一个逻辑表达式，用于判断...
