Why does gcc allow char array initialization with string literal larger than array?

Question

int main()
{
    char a[7] = \"Network\";
    return 0;
}

A string literal in C is terminated internally with a nul charac

Answer 1

The preffered way of declaring a string literal is usually:

   char a[] = "Network";
   printf("size of a: %d\n", sizeof a); // The compiler 'knows' the size of a.
   // this prints '8'

Let the compiler figure it out. It's cumbersome to manually specify the array size and keep it in sync with the string literal's actual length...

So I guess GCC doesn't really bother with anything more than a warning.
