Typedef for 2 dimensional array in C

Is there a way to typedef a 2 dimensional array in C? Something like:

typedef char[10][10] board;

This example doesn't compile. Is there any way to do it? Or any other solution?

Type Definition Statement

The type definition statement is used to allow user defined data types to be defined using other already available data types.

Basic Format: 

typedef existing_data_type new_user_defined_data_type;

So , yours should be :

typedef char board[10][10];

You can use it as Yu Hao has said OR you can also use it with char pointers to define a 2D array like this :

typedef char *board[10];

And then you can do as described by YU Hao. In such a way you need not hard code the number of characters you want to use for the strings.

Try this:

typedef char board[10][10];

Then you can define new array as this:

board double_array = {"hello", "world"};

It's the same with:

char double_array[10][10] = {"hello", "world"};
