C++ STL Quizzes

Last Updated : 14 Apr, 2025

C++ Standard Template Library (STL) provides the inbuilt implementations of commonly used data structures and algorithms. It also provides other components such as iterators and functions to make the programming faster and more robust.

This quiz will help you test your understanding of the key components of the Standard Template Library (STL) such as containers, algorithms, iterators, and function objects.

C++ STL Quizzes

The following list contains topic-wise quizzes from the Standard Template Library in C++:

Templates: Templates are the foundation of the STL. They allow writing generic and reusable code applicable to various data types. This quiz contains 12 MCQs on the topic.
Vector: Vectors are dynamic arrays that allow fast access and flexible resizing. This quiz contains 121 MCQs on the topic.
Forward List: Forward lists offer a lightweight implementation of a singly linked list. This quiz contains 10 MCQs on the topic.
Deque: Deques (double-ended queues) allow insertion and deletion at both ends. This quiz contains 10 MCQs on the topic.
Stack: Queues are FIFO (First In, First Out) data structures. This quiz contains 10 MCQs on the topic.
Queue: Queues are FIFO (First In, First Out) data structures. This quiz contains 10 MCQs on the topic.
Priority Queue: Priority queues manage elements with priority, ensuring the highest-priority element is always accessible. This quiz contains 10 MCQs on the topic.
Set and Multiset: Sets ensure unique element storage while multisets allow duplicates. This quiz contains 10 MCQs on the topic.
Map and Multimap: Maps store key-value pairs for efficient lookup, while multimaps allow multiple entries for a single key. This quiz contains 10 MCQs on the topic.
Unordered Set: Unordered sets provide hash-based storage ensuring faster average lookup times. This quiz contains 10 MCQs on the topic.
Unordered Map: Unordered maps extend the concept of hash-based storage to key-value pairs. This quiz contains 10 MCQs on the topic.
Non-Mutating Algorithms: Non-mutating algorithms do not alter the data but perform computations or queries. This quiz contains 10 MCQs on the topic.
Mutating Algorithms: Mutating algorithms modify the data in containers. This quiz contains 10 MCQs on the topic.
