Thats because array notations are nothing more that pointer arithmetics. That is

that * (A - 1) used to have the size of the array that was allocated! Dont know if

Or it would possibly cause a segfault,
since A can only be legally indexed
by 0..9. (This is assuming it didn't get optimized out).
No. In C, that is actually NOT considered an error by the language! It's
"bad form", but permitted by the language to use array notation to access
memory locations that were NOT allocated to the array!
