带返回的 switch 语句——代码正确性 [英] Switch statement with returns -- code correctness

问题描述

假设我的 C 代码具有大致这种结构:

Let's say I have code in C with approximately this structure:

switch (something)
{
    case 0:
      return "blah";
      break;

    case 1:
    case 4:
      return "foo";
      break;

    case 2:
    case 3:
      return "bar";
      break;

    default:
      return "foobar";
      break;
}

现在显然，break 并不是代码正确运行所必需的，但如果我不把它们放在那里，这似乎是一种不好的做法.

Now obviously, the breaks are not necessary for the code to run correctly, but it sort of looks like bad practice if I don't put them there to me.

你怎么看?删除它们可以吗?或者您会保留它们以提高正确性"吗?

What do you think? Is it fine to remove them? Or would you keep them for increased "correctness"?

推荐答案

删除 break 语句.它们不是必需的，也许某些编译器会发出 无法访问的代码" 警告.

Remove the break statements. They aren't needed and perhaps some compilers will issue "Unreachable code" warnings.
