What are some practical use cases for C++ STL?

C++ STL is widely used for data structures and algorithms. For example, you can use vectors for dynamic arrays, maps for key-value pairs, and algorithms for sorting and searching.

Can you give me an example of using a vector?

Sure! You can use a vector to store a list of integers. For instance, you can create a vector, add elements to it, and then iterate through it to print the values.

What about using maps? How do they work?

Maps in C++ STL store key-value pairs. You can use them to quickly look up values based on a unique key. For example, you can store student names as keys and their grades as values.

Are there any performance benefits to using STL?

Yes, STL provides optimized implementations of data structures and algorithms, which can lead to better performance and reduced development time.
