c++ vectors

#include <iostream>
#include <vector>
 
int main()
{
    // Create a vector containing integers
    std::vector<int> v = { 7, 5, 16, 8 };
 
    // Add two more integers to vector
    v.push_back(25);
    v.push_back(13);
 
    // Print out the vector
    std::cout << "v = { ";
    for (int n : v) {
        std::cout << n << ", ";
    }
    std::cout << "}; 
";
}

Vector in c++

// Create an empty vector
vector<int> vect;

// Create a vector of size n with all values as 10.
vector<int> vect(n, 10);

//initilize with values
vector<int> vect{ 10, 20, 30 };

//initilize with old array
vector<int> vect(arr, arr + n);

//initilize with old vector
vector<int> vect2(vect1.begin(), vect1.end());

vectors c++

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

int main()
{
    // Create a vector containing integers
   vector<int> v = { 7, 5, 16, 8 };
 
    v.push_back(25); // Adds 25 to the contents of the vector 
    v.push_back(13); // Adds 13 to the contents of the vector
 
    // Print out the contents of the vector
    cout << "v = { ";
    for (int n : v) {
        std::cout << n << ", ";
    }
    cout << "}; 
";
}

what do we use c++ vectors for
