请帮忙，在尝试测试我的 C++ 编程作业时遇到问题。任何帮助将不胜感激，我认为这与我在名为 SurroundTheGrid() 的函数中的参数有关

从编译器读取错误消息是一项重要的技能，所以让我们看看我们能从中得到什么。你得到的具体错误是这个：

j:\co 127\assignment 08 adl\assignment 08 adl.cpp(108): error C2660: 'SurroundTheGrid' : function does not take 0 arguments

正如您已经正确解释的那样，这是说问题与您的SurroundTheGrid功能有关。但是，它不是函数本身的声明或定义。问题实际上在于您对该函数的调用之一。

具体来说，错误消息告诉您问题位于文件的第 108 行附近assignment 08 adl.cpp（尽管它为您提供了完整路径，只是为了使消息更长）。

它告诉你你试图调用SurroundTheGrid不带参数的函数，但它实际上需要一些参数（我不知道确切的数字，错误消息没有说）。

据推测，第 108 行发生的事情是你有类似的东西：

SurroundTheGrid();        // passes no arguments to the function -- WRONG!

当你应该有类似的东西时：

SurroundTheGrid(myGrid);  // pass an argument specifying the grid (or something)

由于您没有发布代码，因此我无法在这里详细介绍，但您的猜测是正确的。与错误状态一样，您SurroundTheGrid使用 0 个参数调用函数（所以只有括号，没有任何参数），但该函数不接受 0 个参数。这意味着您应该提供正确数量和类型的参数（同样，我不能告诉您有多少或哪些参数，因为您没有发布代码）。
