What are arrays?

Can someone explain to me what arrays are? So I can understand them? thank you.

An array is a fixed size collection of objects (aka elements). They can be any type that C supports, such as char, int, struct, union, pointers, double, float.

An array is a number of something. For example, a char array would be a number of datatype char. They are convienently numbered in order and referred to with one name. This allows you to work with strings, like "this is a string", because "this is a string" contains 15 characters.

That is a little more cryptic than a definition need be. An array is more like a super block of data that is built out of smaller units chained together.

and for an impromptu definition..."a logically contiguous row of memory locations used for storing data"

I like that definition.

A bunch of something... int array[45] means you have a list of 45 ints. array[0] would be the first and array[n-1] would be the last. Since in this case n = 45, n-1= 44. so array[44] is the last index of the array.
