No, array is a fixed size memory allocation for variables. It is illegal to access elements beyond the allocated space.

Not a great idea, you will be accessing memory which doesn't belong to you or your array, may be used by some other variable with some other meaning/view.

It is purely compiler dependent. It means, some compiler also can take more than one values beyond the end element of the array.

Logically, it doesn't make sense. In practice, you can do this and still get away without CORE being dumped. For example, you defined an array of 10 ints and a single int variable. In most of the compilers, memory is allocated continuously. So, when you refer 11th element of the array as , you are...

Logically, it doesn't make sense. In practice, you can do this and still get away without CORE being dumped. For example, you defined an array of 10 ints and a single int variable. In most of the compilers, memory is allocated continuously. So, when you refer 11th element of the array as [10], you are actually pointing to the next memory location, that is the single int variable, but also belongs to your program. In fact, using array index to access individual array elements is nothing but array arithmetic, with array name being a pointer to the beginning of the array memory locations read less

It's not applicable, if the array has a predefined size. Although it's applicable if using pointer method of array definition, nut still you'll have to allocate memory dynamically before using that index of the array.
