Wondering if this is possible

[Creatlv3]

I just want to know if this is possible, i do not want someone to tell me how to do it.

I am wondering if you can use vectors to store a series of information at a given time
ex)(my homework which is y i just want to know if this is possible)
adding a planet and its information to a vector, then using the push_back() feature to put that vector inside another vector
(vector <double> planet_info() into vector <vector <double> > planet_list)
where planet_info() looks like

double planet_info()
{
   push_back(name(string));
   push_back(mass(string));
   push_back(radius(string));
   push_back(planet_type(string));
   push_back(surface_area(string));
   push_back(density(string));
   push_back(gravity(string));
}

where the push_back() feature calls the function to input the data

There's nothing stopping you from using a vector of vectors, or what looks to be more appropriate here would be a vector of structures.

ok, like i said, i wanted to make sure that this idea would work before i spent several hours wasting my time just to find out that it doesn't work
