Answer:

  1. using namespace std;
  2. struct aaa {
  3.    int m;
  4.    int nn;
  5. };
  6. struct bbb{
  7.    struct aaa myfield;
  8.    int sum;  
  9. };
  10. struct bbb myvar;
  11. int main()
  12. {
  13.    myvar.sum =44;
  14.    myvar.myfield.nn = -17;
  15.    
  16.    cout<<myvar.sum<<"\n";
  17.    cout<<myvar.myfield.nn<<"\n";
  18.    return 0;
  19. }

Explanation:

Given two data structures (Line 2-9), we can set the value of 44 to field of sum structure variable myvar by using a dot syntax

                      myvar.sum = 44

To assign value to field of nn of structure in myvar, we need to access the myfield of myvar and then followed by nn. Hence, the statement shall be

                     myvar.myfield.nn = -17

In short the we can always use the dot syntax the access the value of an inner field of a particular data structure.
