在Visual Basic(VB)中,循环结构用于重复执行一段代码块,直到满足特定条件为止。VB 提供了几种常见的循环结构,包括 For 循环、While 循环、Do While 循环、Do Until 循环,以及用于遍历集合的 For Each 循环。以下是这些循环结构的详细说明和示例: 1. For 循环 For 循环用于在已知迭代次数的情况下重复执行代码块。
i = i + 1 'i增1 Loop Until (i > = n) '判断条件 Print "1到n个整数的和为:" & s '显示累加和 i = 1 '给变量i赋初值 s = 0 '给变量s赋初值 Do While(i < = n) '判断条件 s = s + i '累加i i = i + 1 'i增1 Loop Print "1到n个整数的和为:" & s '显示累加和 End...

Apri in MATLAB Online The code does not work properly. It stops after 2 iterations, instead it should make much more. The idea is: For each main loop to store the value ofx_2whenbetabecomes greater that0.1inx_2_new. Then increaseKand start again: i.e. find the values ofP_1, P_2...
VBA是Visual Basic for Applications的缩写,是一种基于Microsoft Visual Basic的宏语言,用于在Microsoft Office应用程序中编写自定义的宏和脚本。VBA可以用于自动化处理Office文档、创建自定义的用户界面、执行数据分析和处理等。 嵌套do while循环的for循环是一种常见的循环结构,用于在特定条件下重复执行一段代码。嵌套循环...
