When should I use try-catch in C++?

When should I use try-catch in C++?

You should use try-catch blocks in C++ to handle exceptions that may occur during runtime, ensuring your program can recover gracefully.

Can you give me an example of when to use it?

Sure! If you're working with file operations, you might encounter errors if a file doesn't exist. Wrapping the file access code in a try-catch block allows you to handle that error.

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 in your code.

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

Not necessarily. It's best to use try-catch judiciously, only around code that can throw exceptions, to avoid performance overhead.
