What are some effective error handling techniques in C++?

In C++, effective error handling techniques include using exceptions, error codes, and assertions. Would you like to know more about any specific technique?

Can you explain how exceptions work in C++?

Sure! Exceptions in C++ allow you to handle errors gracefully. You can throw an exception when an error occurs and catch it using try-catch blocks. This separates error handling from regular code.

What are error codes and how do they differ from exceptions?

Error codes are integer values returned by functions to indicate success or failure. Unlike exceptions, they require manual checking after each function call, which can lead to less readable code.

Are there any best practices for using assertions?

Yes, assertions should be used to catch programming errors during development. They should not be used for runtime error handling, as they can be disabled in production builds.

Can you give an example of using try-catch in C++?

Certainly! Here's a simple example:

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