What are resource management exceptions in C++?

What are resource management exceptions in C++?

Resource management exceptions in C++ refer to errors that occur during the allocation and deallocation of resources like memory, file handles, etc.

Can you give me an example of how to handle these exceptions?

Sure! You can use try-catch blocks to handle exceptions when allocating resources. For example:

try {
    int* arr = new int[100]; // allocate memory
} catch (const std::bad_alloc& e) {
    std::cerr << "Memory allocation failed: " << e.what() << std::endl;
}

What happens if I don't handle these exceptions?

If you don't handle resource management exceptions, your program may crash or lead to resource leaks, causing undefined behavior.

Are there best practices for resource management in C++?

Yes, using smart pointers like std::unique_ptr and std::shared_ptr can help manage resources automatically and reduce the risk of leaks.
