Reference variable to an array

Write a program to show a use case of a reference variable to an array.

#include<iostream>
using namespace std;
int main()
{
	int a[5] = {11,22,33,44,55};
	int (&p)[5] = a;
	for(int i = 0; i < 5;i++)
	{
		cout << "p[" << i << "] = " << p[i] << endl;
	}
	return 0;
}

Output

p[0] = 11
p[1] = 22
p[2] = 33
p[3] = 44
p[4] = 55
