Have you had experience handling exceptional situations in your projects?

Yes, in my projects I have repeatedly dealt with exception handling, especially when working with dynamic memory and input-output. In C++, try-catch constructs are used for this purpose, allowing to catch exceptions and respond appropriately to errors without causing the program to crash.

Example of handling an exception during memory allocation:

try {
    int* arr = new int[1000000000]; // may throw std::bad_alloc
} catch (const std::bad_alloc& e) {
    std::cerr << "Memory allocation error: " << e.what() << std::endl;
    // error handling, such as resource cleanup or termination
}

I also used custom exception classes for more precise error diagnosis in the program logic.
