推荐答案

引用：

我们的代码中有很多错误，不知道如何解决这个问题

we have alot of errors in our code and don't know how to solve this

这取决于你需要做什么错误。

如果你编译你的应用程序，那么每个错误都会告诉你错误在哪个文件和哪一行，以及描述问题所在。阅读消息，查看代码行，并尝试解决它。谷歌的错误信息，如果你必须，这可以帮助。

当你运行你的代码，然后你需要查看错误本身，并在你的代码运行时看到错误 - 和我们不能为你做那件事。



所以，这取决于你。

幸运的是，你有一个工具可用对你来说，它将帮助你找出发生了什么：调试器。你如何使用它取决于你的编译器系统，但是一个快速的谷歌用于你的IDE名称和调试器应该给你你需要的信息。



放一个断点在函数的第一行，并通过调试器运行代码。然后查看您的代码，并查看您的数据并找出手动应该发生的事情。然后单步执行每一行检查您预期发生的情况正是如此。如果不是，那就是当你遇到问题时，你可以回溯（或者再次运行并仔细观察）以找出原因。


对不起，但我们不能为你做到这一点 - 时间让你学习一门新的（非常非常有用的）技能：调试！

It depends when the errors occur what you need to do.
If it's when you compile your app, then each error will tell you which file and which line the error is on, as well as describing what the problem is. Read the message, look at the line of code, and try to work it out. Google the error message if you have to, that can help.
It the problems happen when you run your code, then you need to look at the error itself, and at your code while it's running - and we can't do that for you.

So, it's going to be up to you.
Fortunately, you have a tool available to you which will help you find out what is going on: the debugger. How you use it depends on your compiler system, but a quick Google for the name of your IDE and "debugger" should give you the info you need.

Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.

Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!
