如何将二维数组从动态更改为特定大小的静态？

I currently have the dynamic array:

我目前有动态数组:

char *myData[500][10]; //myData is the name of an array of[500][10] pointers to type char.  

I would like to create a static 2d array, 500 rows X 10 columns, each element storing memory for 40 characters.

我想创建一个静态2d数组,500行X 10列,每个元素存储40个字符的内存。

Would below be the correct way of declaring that?

以下是宣布这一点的正确方法吗?

char myData[500][10][40];

1 个解决方案

#1

Yes.

But:

• This is a large structure, and declaring it on the stack may not be a good idea

这是一个大型结构,在堆栈上声明它可能不是一个好主意

• This approach has less flexibility that the dynamic version

这种方法的动态版本灵活性较低

• if you mean to use NULL terminated strings with up to 40 characters of data, you should use [500][10][41] to leave room for the \0

如果你的意思是使用带有最多40个字符数据的NULL终止字符串,你应该使用[500] [10] [41]为\ 0留出空间
