I need to have dynamically allocated space of structs and those structs have to contain another dynamically allocated. If I do it by manual allocation, that would laborious.

So I want to do it through vectors: 

using namespace std;

struct lol{
    int value;
    vector<int> vekt;
};

vector<lol> vektt;

It is logically, that I am going to do it like the code above but I dont know how to do 2 things that I am going to need for my program:

1.iterate through both of them to get values

2.push something into vekt( the vector of struct );

I tried something like this for pushing but doesnt work:

vektt[0] . vekt . push_back( 2 );

So I need to know how to iterate through both of these vectors and how to access members and methods of the vector vect.

// Iterating
for (auto &i: vektt)                 // or const auto &i according to requirements
{
    cout << i.value << ", ";
    for (auto j: i.vekt) cout << j << ' ';
    cout << '\n';
}
// Inserting int to vekt of i-th element of vektt
int a;
vektt[i].vekt.push_back(a);
