Study Notes
Abstract Data Types (ADT)
- A combination of data types or structures that form associations and relationships.
- Abstract Data Type (ADT) specifies a set of data along with the operations that can be performed on it.
- Independence from concrete implementations makes ADTs crucial for flexibility.
- Can be defined mathematically or through programming interfaces.
- Interfaces typically provide constructors for creating data and operations on it.
- Common ADTs include String, List, Stack, Queue, Priority Queue, Complex Number, Associative Array, and Multimap.
Lists and Arrays
- A list is a collection of similar data types rather than single variables.
- Lists are essential for managing large amounts of data efficiently, unlike individual variables.
- In C programming, arrays are used as static lists, holding a fixed quantity of elements.
- Example of a static list with integers: 12, 34, 56, 65, 23, 100.
Operations on Lists
-
Addition Operation: Involves adding elements to a static list (array) under certain conditions.
- Index must be less than the array size.
- The index position must not already hold a non-null value to avoid overflow.
-
Algorithm for Addition:
- Step 1: Check if the current index is less than the array size and that it is not filled.
- Step 2: If conditions are met, proceed to add the element; otherwise, output "List overflow or data already exists."
- Step 3: Assign the new element to the array at the current index.
- Step 4: Repeat the process for subsequent elements and indices.
- C implementation sample includes defining an integer array with a function to add elements based on index validation.
