【STL】- vector的使用

 1 #include <vector>
 2 #include <iostream>
 3 using namespace std;
 4 
 5 int ia[] = {123,1,32,53,23,21,45,56,54,223, 669,654};
 6 
 7 int main() {
 8     //initialize
 9     vector<int> vint1;
10     vector<int> vint2(ia, ia+10);
11 
12     //push_back()
13     for(int i = 0; i <=6; ++i)
14         vint1.push_back(i);
15 
16     //size()
17     cout << "The size of vint1 is: " << vint1.size() << endl;
18 
19     //[] operator
20     for(int i = 0; i < vint2.size(); i++)
21         cout << vint2[i] << endl;
22 
23     return 0;
