正在寻找有关我的C++；函数和数组的代码 对于我的C++项目，我已经在这个项目上挣扎了几个星期，我觉得我只是把自己和这个代码中的内容混淆了。有没有人能给我一些关于我做错了什么的指导？以下是我现在遇到的错误： 151 29[错误]无法将“（水果列表*）（&itemsList）”从“水果列表*”转换为“std:：string{aka std:：basic_string}” 152 35[错误]无法将“（水果列表*）（&itemsList）”从“水果列表*”转换为“std:：string{aka std:：basic_string}”

谢谢

我很抱歉，如果代码间距都弄乱了，这是我的第一篇文章，我不断地在我的代码间距上出错？提前道歉

cout它与功能原型无关，而是与结构定义有关

如果你想实际使用一个结构，它必须被完整地定义。在你调用函数之后放置函数定义（实现）是可以的，但是对于结构来说这是不可能的

要声明结构的实际变量，编译器需要结构的完整定义，否则编译器将不知道它包含哪些成员或它有多大

因此，为了解决您的问题，不要在顶部有一个简单的结构前向声明，请将整个结构定义放在那里。
您可以前向声明一个类型（例如
结果列表
）这样编译器就知道它存在，但在你告诉编译器它是如何定义的之前，你不能实际使用它的任何成员。因此你的
struct-foultlist
定义需要在引用结构的任何成员之前出现。谢谢你的帮助！我删除了结构的原型并将结构函数移回但是，当然我现在有两个新错误：151 29[error]无法将（水果列表*）（&itemsList）从“水果列表*”转换为“std:：string{aka std:：basic_string}”152 35[error]无法将（水果列表*）（&itemsList）'从“水果列表*”转换为“std:：string{aka std:：basic_string}”“我正试图浏览我的书，寻找关于我所做的事情的信息，我已经在这门课上挣扎了几周，现在我很困惑。@KatherinePhipps是
showFruitList
函数，它以
FruitList
指针作为参数？它应该这样做吗？如果你有一个像
itemsList
这样的数组，那么就使用e其地址（即
&itemsList
）在大多数情况下都不会像您期望的那样工作。数组自然会衰减为指向其第一个元素的指针，如果您有一个函数需要指向某个结构的指针，只需将数组作为参数传递给该函数就足够了。在修复了其中的所有错误后，我需要做的下一件事是提供指针的使用，而不需要wor关于分配动态内存的问题。我只需要演示如何理解指针在C++语言中的作用。我仍然在学习指针，现在强调我将如何添加它。在哪里，你是说我需要一个来工作，或者现在我不能正确地放置一个指针。
