~ What do you mean?

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

Wave has three forms, one is in the middle of the grid, such as "~"; One is to live on the grid, such as the position in the question; One is the big wave, which is bigger than the previous symbol, such as "~".

Extended data:

In C++ language, the name of the destructor should be the same as the class name, but it is different from the constructor by adding a tilde ~ such as ~stud () in front of the function name. 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 writes 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.
