e) Write a function QDELETE() to perform delete operation on a linked queue
which contains rollno, name of a student. Consider the following definition of

node in the code. struct node 4
{ int rollno;

char name[20];

node *link;
};

Ans: class queue
{
node * rear, *front;
public:
queue()
{rear=front=NULL; }

void qadd();
void qdelete();
};
void queue::qdelete()
{ if( front ==NULL)

cout<<” queue is empty “;
