Boost is an open source library launched by the C + + Standards Committee Library Working Group, which is very powerful. Support regular expressions, multithreaded programming, data structure diagram (STL extension), smart pointers, Python syntax

#include using namespace Std;int &f (){static int i=2; I is a static variable, which is equivalent to a global variable, and he will save the last call value until it is called again, changing his valuereturn ++i;}int g (){int j=2;return ++j;}int

Topic:The algorithm standard library defines a function named Unique_copy, whose operation is similar to unique, except that the former accepts the third iterator argument, which specifies the target sequence for copying the non-repeating element.

For a C + + user, the use of pointers can be counted as commonplace, but in the process of use, many times may be due to new or malloc an object, and forget the end of the time to release (I will make such a mistake), resulting in memory leaks. At
