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

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

Sure! The C++ Standard Library (STL) provides a variety of useful components. For example, you can use the vector class to create dynamic arrays.

How do I add elements to a vector?

You can use the push_back() method to add elements to the end of a vector. For example: myVector.push_back(10);.

What about using maps? Can you show me an example?

Absolutely! You can use std::map to store key-value pairs. Here's a simple example:

std::map<std::string, int> ageMap;
ageMap["Alice"] = 30;
ageMap["Bob"] = 25;

How do I iterate over a map?

You can use a range-based for loop to iterate over a map like this:

for (const auto& pair : ageMap) {
    std::cout << pair.first << " is " << pair.second << " years old.";
}
