Abstract Data Types Quiz

Questions and Answers

What is an abstract data type (ADT)?

A specification of a set of data and the set of operations that can be performed on the data, independent of concrete implementations.

Queue

String

Integer (correct)

A list is a collection of similar data types.

True

Match the following operations with their descriptions:

Addition = Adding an element to the list if conditions are met Overflow = Trying to add an element when the list is full Index = Position in the array where an element is stored Null = Indicates an empty or non-existent value in the list Signup and view all the answers

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.

Description

Test your understanding of abstract data types (ADTs) and their specifications. This quiz covers the combinations of data types, structures, and the operations that can be performed on them. Assess your knowledge on both mathematical definitions and programming interfaces related to ADTs.
