What is move semantics in C++11 and how does it work?

Hi everyone! I started learning C++11 and I keep coming across the term "move semantics", but I can't fully understand what it is and why it's needed. I've read various articles, but the examples everywhere are too abstract.\n\nI have this code. Let's say I'm writing a class that manages a dynamic array:\n\n```cpp\n#include \n#include \n\nclass MyArray {\npublic:\n int* data;\n size_t size;\n\n MyArray(size_t s) : size(s) {\n data = new int[size];\n std::cout << "Constructor called";\n }\n\n MyArray(const MyArray& other) : size(other.size) {\n data = new int[size];\n std::memcpy(data, other.data, size * sizeof(int));\n std::cout << "Copy constructor called";\n }\n\n MyArray& operator=(const MyArray& other) {
