Question

请帮助，在尝试测试我的C ++编程任务时遇到问题。任何帮助都会非常感激，我认为这与我在一个名为SurroundTheGrid（）的函数中的参数有关。

Answer 1

从编译器中读取错误消息是一项重要技能，所以让我们看看我们可以从这个中获得什么。你得到的具体错误就是这个错误：

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，它说这个问题与您的SurroundTheGrid功能有关。但是，它不是函数本身的声明或定义。问题实际上是在函数的一个调用中。

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

它告诉你，你试图在没有参数的情况下调用SurroundTheGrid函数，但它实际上需要一些参数（我不知道确切的数字，错误信息没有说）。

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!

什么时候应该有：

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

Answer 2

我不能在这里详细介绍，因为你没有发布你的代码，但你的猜测是正确的。与错误状态一样，您使用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0参数。这意味着你应该提供正确数量和类型的参数（同样，我不能告诉你有多少或什么参数，因为你没有发布你的代码）。

错误C2660：'SurroundTheGrid'：函数不带0个参数
