How can I manage resources effectively in C++?

Effective resource management in C++ involves using RAII (Resource Acquisition Is Initialization), smart pointers, and proper memory allocation.

What are smart pointers and how do they help?

Smart pointers, like std::unique_ptr and std::shared_ptr, automatically manage memory, preventing leaks and ensuring proper cleanup.

Can you give an example of using a smart pointer?

Sure! Here's a simple example:

#include <memory>

void example() {
    std::unique_ptr<int> ptr = std::make_unique<int>(10);
    // ptr will automatically be deleted when it goes out of scope
}

What should I avoid when managing resources in C++?

Avoid using raw pointers for memory management, as they can lead to memory leaks and undefined behavior if not handled properly.
