How do I throw exceptions in C++?

In C++, you can throw exceptions using the throw keyword followed by an instance of an exception class.

Can you give me an example of throwing and catching an exception?

Sure! Here's a simple example:

#include <iostream>
#include <stdexcept>

void mayGoWrong() {
    bool errorOccurred = true;
    if (errorOccurred) {
        throw std::runtime_error("Something went wrong!");
    }
}

int main() {
    try {
        mayGoWrong();
    } catch (const std::runtime_error& e) {
        std::cout << "Caught an exception: " << e.what() << '\n';
    }
    return 0;
}

What types of exceptions can I throw?

You can throw any type of object, but it's common to throw instances of standard exception classes like std::runtime_error, std::logic_error, or custom exception classes.

Is it a good practice to use exceptions for control flow?

Generally, it's not recommended to use exceptions for regular control flow. They should be used for exceptional circumstances.
