What are some examples of try-catch in C++?

In C++, try-catch blocks are used for exception handling. Here's a simple example:

#include <iostream>
#include <stdexcept>

int main() {
    try {
        throw std::runtime_error("An error occurred");
    } catch (const std::runtime_error& e) {
        std::cout << "Caught: " << e.what() << std::endl;
    }
    return 0;
}

Can you explain how the try-catch block works?

Sure! The try block contains code that might throw an exception, while the catch block handles the exception if it occurs. If an exception is thrown in the try block, control is transferred to the corresponding catch block.

What types of exceptions can I catch?

You can catch standard exceptions like std::runtime_error, std::out_of_range, or even custom exceptions that you define. You can also catch all exceptions using catch (...).

Are there any best practices for using try-catch?

Yes, some best practices include only using try-catch for exceptional cases, not for regular control flow, and ensuring that your catch blocks are specific to the exceptions you expect.
