二维vector源码实现
#include <vector>
#include <iostream>
#include <iterator>
using namespace std;
int main()
{
int N = 2, M = 3;
vector<vector<int> > Matrix(N, vector<int> (M, 0));
ostream_iterator<int> os(cout, " ");
Matrix[0][2] = 4;
//交换矩阵的两行
Matrix[0].swap(Matrix[1]);
//交换矩阵第二行的两个元素
swap(Matrix[1][0], Matrix[1][2]);
for (uint i = 0; i < Matrix.size(); i++)
{
copy(Matrix[i].begin(), Matrix[i].end(), os);
cout << endl;
}
return EXIT_SUCCESS;
