Study Notes
Abstract Data Types (ADTs)
- Solving a problem involves processing data and careful organization of the data to identify the collection of data items and basic operations that must be performed on them.
- An ADT is a collection of data items together with the operations on the data.
- The word "abstract" refers to studying data and basic operations independently of their implementation.
- Focus on what can be done with the data, not how it is done.
Implementation of ADT
- Consists of storage structures to store the data items and algorithms for basic operations.
- Example: Airplane flight with 10 seats to be assigned, where tasks involve listing available seats and reserving a seat.
Data Structures, Abstract Data Types, and Implementations
- Data Structures and Abstract Data Type are often used interchangeably.
- ADT is used when data is studied at a logical level.
- Data structure refers to a construct in programming language used to store data.
Array ADT
- A collection of data elements: a fixed-size sequence of elements, all of the same type.
- Basic operations: direct access to each element in the array by specifying its position.
- One-dimensional array: only one index is used.
- Multi-dimensional array: array involving more than one index.
- Static array: the compiler determines how memory will be allocated for the array.
- Dynamic array: memory allocation takes place during execution.
Array Syntax and Examples
- One-Dimensional Static Array Syntax:
CopyElementType arrayName[CAPACITY];
- Example:
int b[10];
andint b[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
Array as an ADT
- Fixed size: specify the capacity of the array.
- Ordered: indices are numbered 0, 1, 2,..., capacity -1.
- Same type of elements: specify the element type.
- Direct access: subscript operator
[]
.
Array Output Function
- Example:
void display(int array[], int num_values) { for (int i = 0; i < num_values; i++) cout ... }
.
