Classes defined in a function are called local classes. In a local class, only objects and functions in its peripheral scope can be associated. Because variables in the peripheral scope have nothing to do with the objects in the department class,

  An error occurred when the previous DES encryption and decryption class was suddenly decrypted. I couldn't do anything about it. I found this one later. Although it was almost the same, it does, this is really depressing for the previous class.

When macros are used, each parameter is enclosed in parentheses and the overall definition of macros is included. Generally, auto-increment or auto-subtraction operators are not used in macros.   The following are some common macro definitions:   [1]

The format is as follows: Copy Structure  Intcell: intcell (const intcell & RHs) ...{ }   Value assignment overload  Const intcell & intcell: Operator = (const intcell & RHs) ...{ If (this! = & RHs) Storedvalue = RHS. storedvalue;
