How to print two merged int arrays in C++

Answer 1

#include <iostream>
#include <algorithm>
#include <iterator>

using std::cout;
using std::endl;

int main()
{
	int arr1[] = { 0, 1, 2, 3, 3, 4, 6, 8, 8 };
	int len1 = sizeof(arr1) / sizeof(int);

	int arr2[] = { 1, 3, 3, 7, 8, 9 };
	int len2 = sizeof(arr2) / sizeof(int);

	std::merge(arr1, arr1 + len1, arr2, arr2 + len2, std::ostream_iterator<int>(cout, " "));

	cout << endl;

	return 0;
}
