How can I handle errors in C++ STL?

How can I handle errors in C++ STL?

In C++, the Standard Template Library (STL) provides several ways to handle errors, such as using exceptions and checking return values.

What types of exceptions should I be aware of?

You should be aware of standard exceptions like std::out_of_range, std::invalid_argument, and std::bad_alloc.

Can you give me an example of using exceptions with STL containers?

Sure! For example, when accessing an element in a vector, you can use the at() method which throws std::out_of_range if the index is invalid.

What about error handling in algorithms?

For algorithms, you can check the return values or use try-catch blocks to handle exceptions that may arise during execution.
