Vector-Sort

I received a message from HackerRank to solve the Vector-Sort challenge. The requirements call to instantiate a vector of the desired size. Populate and then sort the vector. Once sorted the values in the vector need to be displayed.

Following is a screen capture of a console using the data for sample case:

5
1 6 10 8 4
1 4 6 8 10

Following is my solution written in C++ using Visual Studio 2017 Enterprise Edition:

#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

/*
* Test code.
*/
int main() {

	// **** ****

	int N = 0;

	// **** read N (number of entries for the vector) ****

	cin >> N;

	// **** allocate the vector ****

	vector<int> v(N);

	// **** populate the vector ****

	for (int n = 0; n < N; n++) { cin >> v[n];
	}

	// **** sort the vector ****

	sort(v.begin(), v.end());

	// **** display the sorted contents of the vector ****

	for (int i = 0; i < (int)v.size(); i++) {
		cout << v[i] << " ";
	}
	cout << endl;

	// **** ****

	return 0;
}

The above code passed the eight test cases.

If you have comments or questions, please leave me a message in the section after this post.

Enjoy;
