How could that be?
It is an array but not a string literal, so compiler does not append \0 or
any other extra elements to it.

Hi,

If i give the size of the array as 15, like "unsigned char n[15] =
{'a', 'b', 'c','d'};" , then it is appending '\0'.

Rohit,

Yes, this is perfectly correct.

And this is correct behavior and I was referring to the n[] case only.
Sorry for lack of precision.

Does that mean, that if the size of the array is specified, it appends
'\0' and if it is not specified then it does not append '\0'?
Can you/anyone clarify this point?

I believe Jerzy explained it in details.

Best regards,
