C + + Boolean type in: Boolean type takes only one bit, but if multiple Boolean types are defined consecutively, the compiler may define multiple Boolean types together. The true compiler is represented by a. False The compiler is represented by the.

In the c++98/03 language standard, the compiler needs to instantiate every template that appears in the source code, and the linker will need to remove the duplicated instantiation code when linking. Obviously, it is obviously unnecessary to have

The difference between a class and a struct: The definition class uses the class, which defines the struct body using structs. A struct cannot initialize a field, and a class can. If you do not define a constructor for a class, C #
