C++：scoped_array詳解

The scoped_array class template stores a pointer to a dynamically allocated array.

scoped_array類模板儲存了一個指向動態分配數組的指標, 可以自動析構堆(heap)上所使用的記憶體.

標頭檔: #include <boost/scoped_array.hpp>

代碼:

/*  * 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;  }

輸出:

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