QUESTION : Is empty initialization of array elements in C, allowed ?

What I have tried:

I tried to run the above code on some online IDEs and i got the same results (mentioned above).

Ideone.com - NkJM0W - Online C Compiler & Debugging Tool[^]

I also tried to find the result on Stackoverflow but couldn't understand the answer :
Is an empty initializer list valid C code? - Stack Overflow[^]

As far as I know, it is not allowed, but be careful, the result may depend on compiler.

Here is the reference book by the authors of the language:
The C Programming Language - Wikipedia, the free encyclopedia[^]

It seems rather pointless to have an empty initializer to me. In C and C++ you can write this :

int arr[5]={0};
