vector c++ stl code example
Example 1: c++ vector
#include <vector>
int main() {
std::vector<int> v;
v.push_back(10);
v.push_back(20);
v.pop_back();
v.push_back(30);
auto it = v.begin();
int x = *it;
++it;
int y = *it;
++it;
bool is_end = it == v.end();
return 0;
}
Example 2: how to use vectors c++
#include <iostream>
#include <vector>
using namespace std;
int main() {
const int size = 4;
vector<int> myVect (size, 4);
for (int i=0; i<size; i++) {
cout << "Vector index(" << i <<") is: "<< myVect[i] << endl;
}
return 0;
}
