Can constructors throw exceptions in C++?

Can constructors throw exceptions in C++?

Yes, constructors in C++ can throw exceptions. This is often used to handle errors during object initialization.

What happens if a constructor throws an exception?

If a constructor throws an exception, the object is not created, and the resources allocated during the construction are not released automatically.

How can I handle exceptions thrown by constructors?

You can handle exceptions thrown by constructors using try-catch blocks when you create an object.

Can you give me an example of this?

Sure! Here's a simple example:

class MyClass {
public:
    MyClass() {
        throw std::runtime_error("Error initializing MyClass");
    }
};

int main() {
    try {
        MyClass obj;
    } catch (const std::exception& e) {
        std::cout << e.what();
    }
}
