What are some examples of using the C++ STL?

Can you give me some examples of using the C++ STL?

Sure! The C++ Standard Template Library (STL) provides a variety of data structures and algorithms. For example, you can use std::vector for dynamic arrays, std::map for key-value pairs, and std::set for unique elements.

How do I use std::vector to store integers?

You can declare a vector like this: std::vector<int> myVector;. To add elements, use myVector.push_back(10); and to access elements, use myVector[0];.

What about sorting a vector?

You can sort a vector using the std::sort function. For example: std::sort(myVector.begin(), myVector.end()); will sort the elements in ascending order.

Can you show me an example of using std::map?

Certainly! You can create a map like this: std::map<std::string, int> myMap;. To insert a value, use myMap["apple"] = 5;.
