   cin>>G;

   cout<<endl;

   *gender = tolower(G);

   return 0;

}

//Toss coin(part 2)

bool coin_toss(double seed){

   double r;

   r = (double)seed/(double)RAND_MAX;

   //cout<<r;

   if (r<0.5) return true;

   return false;

}

//check results

When data is being prepared for transmission onto the network, it is broken into small pieces and a header and trailer are added
Archy [21]

Answer:

The correct answer to the following question will be "Encapsulation".

Explanation:

  • Encapsulation relates to the pooling of data with techniques used by the database or the limitation of immediate access to many of the elements of the entity.
  • As data is being processed for transfer to the network, it's split into tiny pieces and a trailer and header are attached to each piece to help determine it.
  • It is a method of shielding data facts and preserving the object's data and actions from abuse by certain objects.

Therefore, Encapsulation is the right answer.
