Problem Statement - 03C

Write the definition of a member function DELETE() for a class QUEUE in C++, to remove a product from a dynamically allocated Queue of products considering the following code is already written as a part of the program.

struct PRODUCT
{
  int PID; char PNAME[20];
  PRODUCT *Next;
};
class QUEUE
{
  PRODUCT *R,*F;
public:
  QUEUE(){R=NULL;F=NULL;}
  void INSERT();
  void DELETE();
  ~QUEUE();
};

Solution

TC++ #5665

 

void QUEUE::DELETE()
{
  if( F!=NULL)
  {
    PRODUCT *T = F;
    cout<<T-> PID<<T->PNAME;
    F=F->Next;
    delete T;
    if(F==NULL) R=NULL;
  }
  else
    cout<<”Queue Empty”;
}
