推荐答案

你有没有理由使用C ++但是试图用C编写代码？

您应该使用C ++字符串对象，类和映射容器。这避免了所有树代码。


如果你用C语言编写，那么使用C #includes和scanf / printf函数。


如果继续使用，请使用调试器逐步执行代码。


C ++可能看起来像：

Is there a reason you are using C++ but are attempting to code in C ?

You should be using be using C++ string objects, classes and a map container. That avoids all of the tree code.

If you are writing in C then use the C #includes and the scanf/printf functions.

If you continue your way, then use your debugger to step through the code.

C++ might kind of look like:

谢谢！


我正在做的是将两者结合起来以简化程序。


我发现我的循环没有正确结束..如果你能看到，并提供关于遍历或搜索部分的输入/纠正。


如果你有时间..请尝试运行我的代码然后你可以看到我面临的错误


谢谢!!

Thank You!

What i am doing is to incorporate both of them for the simplicity of the program.

I have found that my loop is not ending properly.. If you could please see that and give your input/rectification about the traversal or the search part.

If you have time..Please try running my code then you can see the error i am facing

Thank You!!

你提到运行时问题。您是否收到任何编译器警告？


第113行检查症状字段是否为NULL，但症状是char数组而不是char指针。我很惊讶你没有收到编译器警告。同样适用于第133行的其他NULL测试。


您能用文字描述search（）函数背后的意图吗？变量名lchild和rchild建议使用二叉树;但是arr数组看起来不像树。

You mention run-time problems. Are you getting any compiler warnings?

Line 113 checks if the symptom field is NULL, but symptom is a char array not a char pointer. I''m surprised you didn''t get a compiler warning for this. Likewise for other NULL test on line 133.

Can you describe in words the intent behind your search() function? Variable names lchild and rchild suggest a binary tree; but the arr array does not look a tree.
