How do I use try-catch in C++?

In C++, the try-catch block is used for exception handling. You wrap the code that might throw an exception in a try block, and then catch the exception in a catch block.

Can you give me an example?

Sure! Here's a simple example:

#include <iostream>
#include <stdexcept>

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

What types of exceptions can I catch?

You can catch standard exceptions like std::runtime_error, std::logic_error, or any user-defined exceptions. You can also catch all exceptions using catch (...).

Is it a good practice to use try-catch everywhere?

It's best to use try-catch judiciously. Use it for code that can fail, but avoid overusing it as it can make code harder to read and maintain.
