C++Primer3.3.2练习题。

#include <iostream>#include <vector>using namespace std;int main(){vector<int> vc1;for (int i = 0; i<3; i++){vc1.push_back(i);}vector<string> vc2 = { "c", "s", "d", "n" };vector<string> vc3;for (int j = 0; j < vc2.size();j++){vc3.push_back(vc2.at(j));}getchar();return 0;}

为达目的，不则手段。
