how to make a vector in c++

C++
#include <vector>

using namespace std;

int main(){
  vector<int> v;
  //vector<type> name
  
  return 0;
}// First include the vector library:
#include <vector>

// The syntax to create a vector looks like this:
std::vector<type> name;

// We can create & initialize "lol" vector with specific values:
std::vector<double> lol = {66.666, -420.69};

// it would look like this: 66.666 | -420.69
