Chapter 6 branch statements and logical operators Forced type conversion in test conditions As long as these true and false judgments are used, the system will forcibly convert them to the bool type. Therefore, the system will automatically complete

Chapter 8 function Exploration Inline function Selection If the Compilation Time of the function Execution Code is longer than that of the function calling mechanism, the time saved will be only a small part of the whole process. If the code

Constant Declaration P127 constThe constant declaration can be placed in the class definition to make it a member of the class. Constants here are always static (Static), Other objects outside the class can only be accessed through the class name,

C ++ Primer Quick Start 3: several common control statements, primer Quick Start Statements are always executed in sequence: the first statement is executed, followed by the second statement, and the third statement. This is the simplest case. to better control the running of statements, the programming language provides multiple control structures to support more complex statement execution. Let's take a l

Screen class• We can explain inline at the same time as it is declared and defined, but it is actually legal. However, it is best to explain inline only where it is defined outside the class.Variable data membersvariable data members : sometimes (but not often) it happens that we want to be able to modify a data member of a class, that is, within a const member function, and you can do this by adding the mutable keyword to the declaration of the variable.• A mutable data member is never a const,

Introduce const member functions (C ++ Primer P231-232) The constant object of the C ++ class cannot call non-const member functions. To call a member function of a constant object, it must be declared as const: 2. If the const member function returns * this after the end of a
