C++: Rearrange and array in maximum, minimum form

We are given a sorted array and we want to rearrange the array in the form of {max, min, max-1, min+1, max-2, min+2.........}. So here is the code:

	#include<iostream>
	using namespace std;
	void printArray(int arr[], int n);
	void maxMin(int arr[], int n) {
	int arr2[n];
	int mid = n/2;
	for(int i = 0,j = n-1, k =0; i< mid, j>=mid, k<n; k++) {
	if(k%2 != 0) {
	arr2[k] = arr[i];
	i++;
	}
	else {
	arr2[k] = arr[j], j-- ;
	}
	}
	printArray(arr2, n);
	}
	void printArray(int arr[], int n) {
	for(int i = 0; i< n; i++) {
	cout<<arr[i]<<" ";
	}
	}
	int main() {
	int arr[] = {1,2,3,4,5,6,7};
	int n = sizeof(arr)/sizeof(arr[0]);
	maxMin(arr, n);
	return 0;
	}
