Answer 1

String literal is a special, simple, form of writing an array aggregate: you can write "hello" instead of {'h', 'e', 'l', 'l', 'o', '\\0'} (note the terminating zero, which is added automatically).

Note that an array declaration is not only possible, but is sometimes desirable:

char str[] = "hello";
str[0] = 'H'; // OK

lets you modify the string, as opposed to

char *str = "hello";
str[0] = 'H'; // Undefined behavior

which does not allow modifications.
