C++ examples for STL:vector
Demonstrate push_back(), operator[], size() on vector
#include <iostream> #include <vector> using namespace std; int main()//from w w w. ja v a 2 s . c o m { vector<int> v; // create a vector of ints v.push_back(10); // put values at end of array v.push_back(11); v.push_back(12); v.push_back(13); v[0] = 20; // replace with new values v[3] = 23; for(int j=0; j<v.size(); j++) // display vector contents cout << v[j] << ' '; // 20 11 12 23 cout << endl; return 0; }
