What makes you so scared of C/C + +? The C + + language is so powerful and addictive, but the obscure syntax and many programming pitfalls make people scalp numb.Segment ErrorThe most common error we encounter is a segment error, the following is a

A few days ago in the Mushroom Street interview encountered a shuffling algorithm problem, take out and share with you!The original question is: 54 ordered cards, how disorderly to send 3 people?The problem is to use the classic shuffle algorithm to

The solution of #include //n! using namespace std;int giral (int n) {(n>2) && (N*=giral (n-1));//Cannot write n> here 0, because N=0 will return 0, the result of the multiplication will be converted into 0,n>2 than n>1 less once, the efficiency is

is related to machine word length and compiler: Therefore, the width of int,long int,short int may vary depending on the compiler. But there are several ironclad principles (Ansi/iso): 1 sizeof (short int) 16-bit compiler char:1 bytes char* (i.e.

Effective C + + Chapter 1. Make yourself accustomed to C + + (Accustoming yourself to C + +) Item 1. View C + + as a language federation (View C + + as a federation of Languages) Consider C + + as a federation of four sub-languages, where codes and

BackgroundBackgroundC + + is the main development language used by many of Google ' s open-source projects. As every C + + programmer knows, the language have many powerful features, but this power brings with it complexity, which in Turn can make

/* Write a function that passes a variable of type A, b two int, and returns a greatest common divisor of two values. For example: the input incoming (0, 5) function returns 5, the incoming (10, 9) function returns 1, the Incoming (12, 4) function

Original: http://www.seacha.com/article.php/knowledge/cbase/2013/0903/2205.html C + + vector (vector container) is a linear sequential structure. Equivalent to an array, but its size can be unspecified and automatically expanded. It can

The alternative scheme of virtual function includes NVI technique and strategy design mode. The NVI technique itself is a special form of template method design mode.One drawback of moving functions from member functions to class external functions

Summary:A question about the container adapter.Just beginning to contact the container adapter, always feel strange, think superfluous, handy search, originally I was not alone at this point:Use of STL container adaptersOne of the guys said well,
