Arrays use a Base Pointer and an Index. They are calculated using the notation BP+IDX*Size, where IDX 0 is the first index location, and Size is the size of each element (at a hardware level, the size is determined by the register the data is loaded into). Languages that start array indexes at 0 use this hardware notation. Other languages start at 1 as a means of being "human friendly", since the zeroth location is the primary cause for developers going "out of bounds" on an array (they forget that the size of the array is one larger than the last index of the array).
Matrix arithmetic calculations, which are very common in all fields of engineering, would be difficult to code without arrays.
It is because array name implies its address and if you want to access first element of it pointer address logic is as below: Arrays first element address = array base address + 0 Arrays second element address = array base address + 1
It is accessing data by address.
A cell address identifies a particular cell. It can be used in formulas to help in calculations. By using the cell address you can access the value in the cell.A cell address identifies a particular cell. It can be used in formulas to help in calculations.

That's what & operator is good for: gives you the address of the variables.
yes
You don't need to use ampersand for arrays; it's entirely optional even for strings (character arrays). This is because arrays will implicitly convert to a pointer at the slightest provocation. Thus for an array named X, you can either pass the array to a function as X, &X or &X[0], they all refer to the exact same address.
Arrays having more than one dimension is known as multi-dimensional arrays. Multi-dimensional arrays is also known as arrays-of-arrays.

An index register contains an address that can be used during effective address generation, often along with an offset in the instruction or in another register. This is most useful when accessing elements of arrays or structures. A stack pointer is a specialized index register that points to a region of memory that can store temporary elements, in a last-in-first-out structure, such as return addresses, parameters, and local storage for function calls.
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.
Arrays are reported to be omnivoire.
