Answer 1

Here is the code that works. I specify the size of the vector when I construct it.

    vector v(n);

Compile code:

#include
using namespace std;
struct s{
    int a;
    int d;
};

int main(){
        int n;
        cin>>n;
        vector v(n);
        for(int i=0;i>v[i].a;
        }
        for(int i=0;i>v[i].d;
        }
    return 0;
}
