What is the farming symbol?

The English symbol of ~ is called tilde, which means tilled symbol, nasalized symbol and Dai font size. It is commonly known as Tilde in Chinese.

Generally, when typing with chat tools, I like to add "~" at the end, which reflects the trend of contemporary teenagers. Reflect endless ambiguity, ambiguity, happiness, etc. Most of these chats are cute girls and younger brothers, such as the popular cute girls, warm men and small fresh meat, which basically belong to this category.

~ can also be used to indicate a range. For example: 10~ 14 years old, 600~700.

~ ~ is an expression and has no practical significance. Usually, when the other party says something that can't be answered in online chat, it is a common phrase as a response or bubbling.

Programming aspect

Destructors are the opposite of constructors. When the object is out of its scope (for example, the function where the object is located has been called), the system automatically executes the destructor. Destructors are often used to "clean up the mess" (for example, when creating an object, open a memory space with new, and should be released in the destructor with delete before exiting).

Take C++ as an example, the name of the destructor should be the same as the class name, but it is different from the constructor by adding a tilde ~ before the function name, such as ~stud (). It cannot take any parameters and has no return value (including void type). There can only be one destructor and it cannot be overloaded.

If the user does not write a destructor, the compiler will automatically generate a default destructor, which does nothing. So many simple classes do not use explicit destructors.

In C/C++ language, ~ is aNOTher operator-binary bitwise not operator. For example: int x = 0x79；; Write binary 01111001; The result of ~x operation is 10000 1 10. That is, if a bit is 1, it will become 0; If it is 0, it becomes 1.
