What does this symbol mean?

Destructuring, which is generally used as a destructor.

Destructor, in contrast to constructor, automatically executes a destructor when an object is out of its scope, such as when the function in which the object is located has been called. Destructors are often used to do the work of "cleaning up the aftermath" (e.g. creating an object with new to open up a piece of memory space, which should be released in the destructor with delete before exiting).

In the case of C++, the destructor name should also be the same as the class name, except with a tilde in front of the function name, such as stud( ) to distinguish it from the constructor. It can't have any arguments and doesn't return a value (including the void type). There can only be one destructor, it cannot be overloaded.

If you don't write a destructor, the compilation system automatically generates a default destructor and does nothing. So many simple classes don't use explicit destructors.
