First, the concept of enumerationsEnumerations are a basic data type in the C language, not a constructed type, which can be used to declare a set of constants. When a variable has several fixed possible values, the variable can be defined as an

The derivation of the definition of const and define in a variable to the incline in a function segmentNote the difference between an inline function and a function callWhat is an inline function?Inline (caution, not online), translated into "inline"

Then review the functions, pointers, and applications.Function1, multidimensional arrays as formal parameters, the size of the first dimension can be omitted (or not omitted), but the size of the other dimensions must be specified. such as

The compiler always generates a default constructor when there is no constructor for error cognition The compiler generates a default constructor only when necessaryThe same as the destructor Conditions: There is a member with

When writing a program, we often say that the underlying type variable exists in the stack memory, and that the variable (object, array) of the reference type has heap memory. Now let's see how this data structure of the stack is

In this section we discuss two interesting data structures, stacks, and queues.What is a stack, the so-called Stack is a stack (stack) that operates on a linear table that is scoped to the end of the table. The end of the table is inserted, deleted,

Introduction: This is the basis of C + + object memory allocation, to prevent forgetting.See how a class is constructed when it contains other classes.#include using namespacestd;classobject{ Public: Object () {cout"Object:"Endl; } ~Object ()
