Initialize array of strings with \0

Question

I would like to initialize an array of strings with \0. Is it right to do it like this?

char first[1024][1024] = {'\0'};

@Arpit: I'm not seeing a static, so I'm not sure what you're talking about. — user2357112

For a 2d array is better to use:

char first[1024][1024] = {{'\0'},{'\0'}};

or better yet (as suggested by @haccks):

char first[1024][1024] = {{'\0'}};

in order to avoid warnings.

@haccks, sorry for rollback your edit, but gcc gives a warning using {'\0'}

@AlterMann; Interesting!

@haccks, edited, you are right, compiles without warning and I was trying char first[1024][1024] = {'\0'};

If it is a static array, say, a global array, you do not need to do any initialization and the values of the array are set to 0 by default.

It cannot be judged the array in the question is static or not from the expression of the question, so why you are sure that it is not a static array? @lgor
