C++

Many examples were found when writing makefile, some of which Bash was CC, and some were GCC, and then went through some of the relevant data. The original CC is the C compiler under UNIX, and GCC is the compiler under Linux. So the question is, are

For normal types of objects, replication between them is simple, for example:int a=100;int b=a;And the class object is different from ordinary object, the inner structure of class object is generally more complex, there are various member variables.

Because of the need for some multi-threaded C + + crawler before the multithreading did not use mutex, and then there are some problems is, repeatedly downloaded the page ... I found this piece of code on the Internet, so I wrote a blog to share it

#include intSump (int*,int*);intMainvoid){ intArray[] = {1,3,4,7,8}; printf ("total=%d\n", Sump (array,array+5)); return 0;}intSump (int* Start,int*end) { intTotal =0; while(startend) Total+ = *start++; returnTotal ;}Sump Method Description:1

Use standard C + + type conversions: static_cast, dynamic_cast, reinterpret_cast, and const_cast.1, static_castUsage:static_cast (expression)The operator converts expression to the Type-id type,But there is no run-time type check to guarantee the

Here the direct addressing method is used to go through the list, if the corresponding array position value is 0, then the correction is 1, if the corresponding array is 1, then delete the node. (array initialized to 0)Some of the operations of the

1) PrefaceIn my study of C + +, the control of the members of the class has always been a point of headache, a public, a will and private, there are protected, and then add inheritance, but also has the common inheritance, private inheritance,

There is no such nonsense as value types and reference types in C, only the concept of variables. A variable represents a named storage area. C + + does have a reference concept and syntax, but the underlying is basically a pointer

Using an array representation for each property, most groups can represent a set of isomorphic objects. The pointer is placed in an extra array, denoted by a subscript.This implementation code is based on 10.3-5, mainly in order to implement the

#include using namespace std;struct node{int data; Node * NEXT; Node (int x=0):d ata (x), Next (NULL) {}};class list{public: List () {first = new Node ();} void Insert (int x) {Node *s = new Node (x); s->next = First->next;first->next = s;} void

Implement an address book;Contacts can be used to store 1000 of people's information, and each person's information includes:Name, gender, age, telephone, addressAvailable methods:1. Add contact information2. Delete the specified contact information3

The first time to record technology-related knowledge, I believe that the future will be able to see their progress!I've been busy looking for a job because I have to deal with various written tests. So do a few exercises, do not know how to

"Function pointer"In the program run, the function code is the program's algorithm instruction part, they and the array also occupies the storage space, has the corresponding address. You can use pointer variables to point to the first address of an

C # does not allow the values of elements in the array or collection to be altered in the Foreach Loop (note: The value of the member is not affected), as the following code will not compile.(in MyArray){x//error code because the value of the

Let's take a look at the following code:#include using namespace Std;class point{public:point (float x=0.0,float y=0.0): _x (x), _y (y) {}point & operator= (const point& RHS), void Printdata () {coutThe program output results are as follows:Parsing:

1, reference base class object directly with base class pointer2, referencing derived class objects directly with derived class pointers3, reference a derived class object with a base-class pointer, because the derived class object is also an object

The Google C + + programming style manual mentions many of the issues that you need to be aware of when programming, and it can be helpful to standardize your code. Here are some reading notes, but also a summary of some of the points.-Google C + +
