Vector of struct

[ldima]

Hello everyone,
I have a struct that is a vector of struct,defined as:

struct a{
  int b;
  int c;
};

struct d{
  vector<a> e;
  vector<a> f;
};

now i want to assign values to vectors,like for example

d example;
example.e[0].b=10;

how can I do this?
thanks for helping

example.e.push_back( a() );

example.e[0].b = 10;
