Why C++ programmers should minimize the use of `new`

Hello, colleagues! I'm a beginner C++ developer trying to understand best practices. Everywhere I read that I should avoid `new`, but I don't fully understand the reason. In textbooks they often write: "allocate memory on the heap using `new`", and then experienced developers say: "don't do that". This confuses me. Here's a simple example: I need to create an object that will live longer than the current function. I write: ```cpp class MyClass { public: MyClass() { std::cout << "Created\n"; } ~MyClass() { std::cout << "Destroyed\n"; } void doWork() { /* ... */ } }; void process() { MyClass* obj = new MyClass(); obj->doWork(); // Forgot delete! Memory leak. } ``` Problem: I often forget to call `delete`, and this leads to memory leaks. I've also heard that `new` can throw exceptions...
