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 for 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';

    }

}

Output:

10

5

8

4

1

2

15

30

Deleting a Single Value

Write a program that defines a vector of integers. Erase the second element ...
