C++: Array Concatenation

Show how to concatenate two arrays in your language. If this is as simple as array1 + array2, so be it.

#include <vector>
#include <iostream>

int main()
{
	std::vector<int> a(3), b(4);
	a[0] = 11; a[1] = 12; a[2] = 13;
	b[0] = 21; b[1] = 22; b[2] = 23; b[3] = 24;

	a.insert(a.end(), b.begin(), b.end());

	for (int i = 0; i < a.size(); ++i)
	std::cout << "a[" << i << "] = " << a[i] << "\n";
}
