错误C2660：'SurroundTheGrid'：函数不需要0个参数

Question

请帮忙，在尝试测试我的C++编程任务时遇到问题。任何帮助将不胜感激，我想它是与我的论点在一个名为SurroundTheGrid（）的函数

Answer 1

从编译器读取错误消息是一项重要的技能，所以我们来看看我们可以从中得到什么。你得到特定的错误是这一个：

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

正如你已经正确的解释，它说，这个问题有事情做与你SurroundTheGrid功能。但是，这不是函数本身的声明或定义。问题其实是在你的调用的函数之一。

具体而言，错误消息告诉您问题位于文件assignment 08 adl.cpp的第108行的周围（尽管它为您提供了使消息更长的完整路径）。

它告诉你，你试图调用没有参数的SurroundTheGrid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，发生了什么事就行108是你有这样的：

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

当你应该是这样的：

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

Answer 2

因为您没有发布您的代码，所以我不能在这里详细讨论，但您的猜测是正确的。就像错误状态一样，你使用0个参数调用函数SurroundTheGrid（所以只是括号，没有任何参数），但函数不接受0个参数。这意味着你应该提供正确的数量和类型的参数（再次，我不能告诉你多少或什么参数，因为你没有发布你的代码）。
