C++：scoped_array详解

C++：scoped_array详解2014-11-14The scoped_array class template stores a pointer to a dynamically allocated array.

scoped_array类模板存储了一个指向动态分配数组的指针, 可以自动析构堆（heap）上所使用的内存.

头文件: #include <boost/scoped_array.hpp>

代码:

/** test.cpp**Created on: 2014.04.18*Author: Spike*//*eclipse cdt, gcc 4.8.1*/#include <iostream>#include <boost/scoped_array.hpp>using namespace std;int main（） {const int n（3）;boost::scoped_array<int> pData（new int[n*n]）;int temp[9] = {0, 1, 2, 3, 4, 5, 6, 7, 8};pData.reset（temp）;for （std::size_t i=0; i<n*n; ++i） {std::cout << "pData[" << i << "] = " << pData[i] << std::endl;}return 0;}

输出:

pData[0] = 0pData[1] = 1pData[2] = 2pData[3] = 3pData[4] = 4pData[5] = 5pData[6] = 6pData[7] = 7pData[8] = 8
