How do I get started with C++ STL?

To get started with C++ STL, you should first understand the basic components like vectors, lists, and maps.

What are vectors in C++ STL?

Vectors are dynamic arrays that can grow in size. They provide random access to elements and are part of the STL.

Can you show me an example of using a vector?

Sure! Here's a simple example:

#include <iostream>
#include <vector>

int main() {
    std::vector<int> numbers;
    numbers.push_back(10);
    numbers.push_back(20);
    std::cout << numbers[0] << std::endl; // Outputs 10
    return 0;
}

What other containers are available in STL?

Other than vectors, STL includes lists, deques, sets, maps, and more, each serving different purposes.
