Push and print elements in an integer vector

In this example, we are declaring an integer vector, pushing the elements using a for loop with the counter starting value from 1 to 5 and then printing the value separated by space.

Example

#include <iostream>
#include <vector> //for vector
using namespace std;

int main()
{
    // vector  for integer elements
    vector<int> v1;

    // adding 5 elements
    for (int i = 1; i <= 5; ++i) {
        v1.push_back(i);
    }

    // print all elements
    cout << "vector elements are: ";
    for (int i = 0; i < v1.size(); ++i) {
        cout << v1[i] << ' ';
    }
    cout << endl;

    return 0;
}

Output

vector elements are: 1 2 3 4 5
