39.1 Basic Vector

Write a program that defines a vector of integers. Insert two elements into a vector. Print out the vector content using the range-based loop .

#include <iostream>

#include <vector>

int main()

{

    std::vector<int> v = { 10, 5, 8, 4, 1, 2 };

    v.push_back(15); // insert the value 15

    v.push_back(30); // insert the value of 30

    for (auto el : v)

    {

        std::cout << el << '\n';

    }

}

39.2 Deleting a Single Value

Write a program that defines a vector of integers. Erase the second element from the vector. Print out the vector content using the range-based loop
