What are the exceptions in the C++ Standard Library?

The C++ Standard Library defines several exceptions, primarily derived from the std::exception class. Common ones include std::runtime_error, std::logic_error, and std::out_of_range. Each serves a specific purpose for error handling.

Can you explain the difference between runtime_error and logic_error?

Certainly! std::runtime_error is used for errors that occur during program execution, while std::logic_error is for errors in the program's logic, such as violations of preconditions or invariants.

How do I handle these exceptions in my code?

You can handle exceptions using try-catch blocks. For example:

try {
    // code that may throw an exception
} catch (const std::exception& e) {
    std::cerr << "Error: " << e.what() << std::endl;
}

Are there any best practices for using exceptions in C++?

Yes, some best practices include using exceptions for exceptional cases only, avoiding exceptions in destructors, and providing meaningful error messages.
