C++ Try Catch 内循环 [英] C++ Try Catch inside loop

问题描述

我有一个具有以下一般结构的 C++ 程序

I have this C++ program with the following general structure

1st while (condition A == true)
  //some code for 1st loop

  2nd while (condition B == true)
    //some code for 2nd loop
    try
      //some code for try
    catch
      //condition B == false (supposed to leave 2nd loop and go back to first loop)

我希望它在出现异常时退出第二个循环并返回到第一个循环，直到条件 B 再次出现.如上所述，它不像我预期的那样工作.似乎正在发生的事情是代码卡在 catch 中并且永远不会离开它.

I want it to get out of 2nd loop when there's an exception and go back to 1st loop until condition B is tue again. As described above it doesn't work as I expect. What seems to be happening is that code gets stuck in catch and never leaves it.

我如何安排它以使其按照我的需要工作?

How can I arrange it to make it work as I need?

注意:条件 A 永远不会为假.

Note: condition A is never false.

推荐答案

在 catch 中添加 break 关键字

add the break keyword to the catch

还要注意你有 b == false;那就是检查 b 是否等于 false，而不是设置 b = false.

Also notice that you have b == false; That is checking that b is equal to false, not setting b = false.
