Question 1

What is the main purpose of the C++ Standard Template Library (STL)?

A: To provide a set of predefined functions B: To simplify the process of programming in C++ C: To handle user interface design

Correct: B Explanation: The C++ Standard Template Library (STL) aims to simplify the process of programming in C++ by providing a set of predefined templates, containers, algorithms, iterators, and function objects.

Now, let's dive into the world of STL containers! šŸŒŠ

cpp
#include <iostream> #include <vector> // Include STL containers #include <algorithm> // Include STL algorithms int main() { std::vector<int> numbers = {1, 2, 3, 4, 5}; // Creating a vector of integers // Printing the initial vector for (int i = 0; i < numbers.size(); ++i) { std::cout << numbers[i] << " "; } std::cout << std::endl; // Sorting the vector using STL sort algorithm std::sort(numbers.begin(), numbers.end()); // Printing the sorted vector for (int i = 0; i < numbers.size(); ++i) { std::cout << numbers[i] << " "; } return 0; }

In the above code, we create a std::vector of integers, sort it using the std::sort algorithm, and print the sorted vector. This is just the beginning of our exploration into the C++ Standard Template Library!
