Delete an element from an array

/*
 * C program to delete an element from array at specified position
 */

#include <stdio.h>
#define MAX_SIZE 100
//this code does not literally delete an element 
//this does rewrite the rest of the array over the element to be deleted 
//and reduceing the count by one
