Question

What is the difference between an array (not any particular language's implementation of array, but the abstract array) and a list?

Answer 1

a list is quite diverse than an array.....an array is a sequential data type with similar data type were as a list (though not uniquely defined as it depends on platform) is not a data type rather it classifies the program methodoligies

Answer 2

An array is usually just contiguous block of memory where each 'element' just represents the size in bytes of whatever type of array it is. In C, think of a string as a fixed size array of chars with a null at the end to announce the end of the array. A list is obviously more advanced as it supports extra features, for example it might have a length property, it might be easier to insert an element somewhere in the middle of the list or it would be easier to resize the list.
