Study Notes
Arrays in Programming
- An array is a data structure that stores a collection of elements, each identified by an index or key.
- Elements in an array are uniquely identified by their index or subscript, which is a numerical value that corresponds to a specific position in the array.
- Arrays and lists describe a collection of elements that are stored and manipulated as a single unit in programming.
- An array can be compared to a staircase, where each step represents an element in the array, and the index or subscript corresponds to the step number.
- The main characteristic of an array is that it stores a fixed-size, homogeneous collection of elements, meaning all elements must be of the same data type.
