如何在C中声明常量2D字符串数组 [英] How to declare a constant 2d string array in C

问题描述

我具有以下数组结构:

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

我想在C中声明它，我已经这样做了:

I want to declare it in C , I have done it like this :

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

但是我遇到了这个错误:数组的元素类型不完整.什么是实现此目的的正确方法(声明和访问(打印)).我必须采用三维数组吗?

But I am getting this error : array has incomplete element type. What is the right way of achieving this(declaring and accessing (printing)).Do I have to take three dimensional array?

推荐答案

在C中，定义二维数组时必须指定列大小.看一下这个问题:

In C, you have to specify the column size when defining a two dimensional array. Take a look at this question: 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"}
                       };
