(b) What is a priority queue? Give two types of priority queues.

(c) The following program does the following:

1. Create a queue, q, consisting of 1 (front), 2, 3, 4 and 5 (rear).

2. Display the contents of q.

3. Remove an item from q and display the content of q.

#include

#include

#define MAXQUEUE 6

#define TRUE 1

#define FALSE 0

struct queue

{

int items[MAXQUEUE];

int front, rear;

};

void initialize();

int empty();

void insert();

int rem();

void output();

int n;

void main()

{

struct queue q;

int i,E;

initialize(&q);

printf("Enter the number of elements: ");

scanf("%d",&n);

If (n

{

for(i=0;i

{

printf("Enter an element: ");

scanf("%d",&E);

insert(&q,E);

}

}

else

{

printf("Number of elements must be less than MAXQUEUE.\n");

return;

}

printf("\nContent of the Queue from Front to Rear: ");

output(&q);

rem(&q);

printf("\nContent of the Queue from Front to Rear: ");

output(&q);

}

Write the functions initialize, empty, insert and rem in C.
