Where is the null character in an empty string with a fixed length?

Question

So, I was curious to read the C code; let's say we have the following code:

char text[10] = "";

Where does the C compiler then put the null character?

I can think of 3 possible cases

• At the beginning, and then 9 characters of what was previously remembered
• In the end, so 9 characters of garbage and then trailing '\0'
• He completely fills it 10 '\0'

The question, depending on any case, is whether to add a final one '\0'at runtime strncpy. If this is case 2 and 3, then this is not necessary, but a good idea; and if this is case 1, then this is absolutely necessary.

What is it?
