pointers and references

ReferenceAndPointerYesC ++A very important concept in programming language may be difficult for beginners. The following describes pointers and references in detail. There are three differences between references and pointers: 1 The reference must

I. CONSTEXPR and constant expressionsConstant expressions (const expression) are expressions that do not change the value and can be evaluated in the compilation process. Obviously, literals are constant expressions, and const objects initialized

This chapter introduces the sequential containers, in the previous chapter, the learned vectors belong to one of the sequential containers.a container is a collection of certain types of objects .In addition to vectors, what are the sequential

To support the polymorphism of C + +, dynamic binding and static binding are used. Understanding their differences can help to better understand polymorphism and avoid making mistakes during programming.There are four nouns to understand:1. Static

I haven't written an article in a long time.first send the notes of last month:)Basic Type Constantsconst int A; int const A; const int *a; int * const A; int const * a const; const int A; int const A; The two formulations are identical, indicating

14.1 Definition of overloaded operatorsThe operator cannot be overloaded:. ?: sizeof::. *Additional new operators cannot be defined for any built-in type; precedence and binding are fixed; no short-circuit evaluation feature is recommended (no

ActionScript3 (AS3 for short) and c ++ are both Object-Oriented Programming (OOP) languages with OOP features such as encapsulation, inheritance, and polymorphism. There are many similarities in the syntax between the two. It is not very difficult

The first part1.Please describe the difference between a value type and a reference typeAnswer: difference:1. The value type is stored in the memory stack, the reference type data is stored in the memory heap, and the memory unit holds the address

function, how do the arrays pass the arguments?It is not possible for the entire array to pass through. Naturally associative to pointers and references. Because the array pointer is essentially a multi-pointer, the following three types of

1. Functions defined inside the class implicitly feel inline, the inline function should be defined in the header file, because its definition must be visible to the compiler, so that the compiler can expand the code of the function within the call

Go from blog: http://blog.csdn.net/wangweitingaabbcc/article/details/7720979#In the world of C + + There are two concepts, the upward type conversion, the downward type conversion, respectively describing the subclass to the base class, and the base

Now suppose that a B inherits from a , sob* can be used as a *. Similarly, a b& can be used as a a&. However, a A is not necessarily a B, so a* cannot be used as a b*. In general, if a class derived has a public base class base, then we can assign

In the procedural field, there is a sentence, the procedure is better, the bug is difficult to adjust.Many bugs are not logic errors, but some details.We analyze the inability to run the problem caused by three details errors:#define M_PI 3. 14159265

Template definition: A template is a tool for implementing the code reuse mechanism, which can implement type parameterization, that is, to define the type as a parameter, thus enabling real code reusability. Template can be divided into two
