The new operator is used in C to dynamically allocate memory and returns a pointer to the newly allocated memory. When new is used to create an object, it automatically calls the object's constructor for initialization.

For example:

int* p = new int(10); // 分配一个int类型的内存空间，值为10，并返回一个指向它的指针

In this example, new allocates a memory that can store int type, initializes it to 10, and then returns a pointer to this memory. The pointer is stored in int* p.

It should be noted that memory allocated using new needs to be released using delete when no longer in use to avoid memory leaks.

delete p; // 释放内存
