1. What is an identifierIdentifiers are some of the symbols and names that you customize in your program. To differentiate from keywords: the keyword is the symbol that is provided by the C language by default, and the identifier is a

Easy to forget knowledge points: The destructor generated by the compiler is not a virtual destructor unless the base class of the class itself declares a virtual destructor. If a base class declares an assignment operator as private,

1. Arithmetic conversionMany operators throw conversions that produce a result type in a similar way, which is called an "ordinary arithmetic conversion".First, any operand of type char or short is converted to int, and any operand of type float is

C ++ references function parameters as function parameters A reference can also be used as a function parameter. For example, we define the swap function to exchange two numbers and define the function parameters as references: 1 void swap (int & p1,
