How do I use the Standard Template Library in C++?

The Standard Template Library (STL) in C++ provides a set of common classes and interfaces for data structures and algorithms. What specific aspect of STL are you interested in?

Can you explain how to use vectors?

Sure! Vectors in STL are dynamic arrays that can resize themselves. You can include the vector header and use it like this:

#include <vector>
std::vector<int> myVector;
myVector.push_back(10);
myVector.push_back(20);

Would you like to know more about other STL containers?

Yes, what about maps?

Maps are associative containers that store elements in key-value pairs. You can use them like this:

#include <map>
std::map<std::string, int> myMap;
myMap["apple"] = 1;
myMap["banana"] = 2;

Do you want to learn about iterating through maps?

That would be great!

To iterate through a map, you can use a for loop like this:

for (const auto& pair : myMap) {
    std::cout << pair.first << " : " << pair.second << std::endl;
}

This will print each key-value pair. Any other STL topics you're curious about?
