Implements Queue in C language

C language is always very useful to implements data structure. This program will be highly helpful for the students and professional to use queue using C language.

#include <stdio.h>
#include<stdlib.h>
#define MAX 9
void push(int queue[],int *front,int *rear,int item)
{
 if((*front==0 && *rear==MAX) || (*rear+1==*front))
 {
  printf("\nOver Flow.....");
  return;
 }
 else if(*front==-1)
 {
  *front=0;
  *rear=0;
 }
 else if(*rear==MAX)
 {
  *rear=0;
 }
 else
 {
  *rear=*rear+1;
 }
 queue[*rear]=item;
}
int pop(int queue[],int *front,int *rear)
{
 int a;
 if(*front==-1)
 {
  printf("\nUnder flow......");
  return -1;
 }
 else
 {
 a=queue[*front];

 }
 else if(*front==*rear)

 int c;
 printf("\n1.Insert\n2.Delete\n3.Display\n4.Exit");
 printf("\nEnter your choice: ");

    push(queue,&front,&rear,item);
    break;
   case 2:
    item=pop(queue,&front,&rear);
    if(item!=-1)
    {
     printf("%d has been deleted...",item);
    }
    break;
