c - 如何在 C 中声明一个常量二维字符串数组

Question

我有以下数组结构:

left , right , top
top , left , right 
top , top , left 

我想在 C 中声明它，我已经这样做了:

char *movements[][] = {{"left","right","top"},
                        {"top","left","right"},
                        {"top","top","top"}
                       }

但我收到此错误:数组的元素类型不完整。实现此目的的正确方法是什么(声明和访问(打印))。我必须采用三维数组吗？

在C 语言中，定义二维数组时必须指定列的大小。看看这个问题:Why do we need to specify the column size when passing a 2D array as a parameter?

char *movements[][3] = {
                           {"left","right","top"},
                           {"top","left","right"},
                           {"top","top","top"}
                       };
