Find even occurring elements in an array of limited range

Here given code implementation process.

// C Program

// Element value between 0 to 31
#include <stdio.h>

	int xors = 0;

	int i = 0;
	// Execute loop through by array size
	for (i = 0; i < n; ++i)
	{

		{

			return;
		}
		// Left shift of number 1 by array element 
		location = 1 << data[i];

	for (i = 0; i < n; ++i)
	{
