Why and when can I use Arrays? Is this necessary for all the programs?

Question

I'm so lost...

Answer 1

Array is not necessary but Its a good habit to use them. As in a situation where you requires many variables of same datatype it is wiser to GI for array rather then declaring each variable. For ex to store total marks of students of class 50 array is wiser choice.

Answer 2

it is useful for sum and stuff like that.. it is not at all necessary for all programs

Answer 3

it's necessary to manipulate data binding.
