Problem Statement - 04B

Write a definition for function ONOFFER( ) in C++ to read each object of a binary file TOYS.DAT, find and display details of those toys, which has status as “ÖN OFFER”. Assume that the file TOYS.DAT is created with the help of objects of class TOYS, which is defined below:

class TOYS
{
  int TID;char Toy[20],Status[20]; float MRP;
  public:
  void Getinstock()
  {
    cin>>TID;gets(Toy);gets(Status);cin>>MRP;
  }
  void View()
  {
    cout<<TID<<”:”<<Toy<<”:”<<MRP<<””:”<<Status<<endl;
  }
  char *SeeOffer() { return Status; }
};

Solution

TC++ #5686

void ONOFFER()
{
  TOYS T;
  ifstream fin;
  fin.open(“TOYS.DAT”, ios::binary);
  while(fin.read((char*)&T, sizeof(T)))
  {
    if(strcmp(T.SeeOffer(),”ON OFFER”)==0)
    T.View();
  }
  fin.close(); //Ignore
}

OR
Any other correct function definition
