Array Sort using c++

Source code:

#include <algorithm> // for std::swap, use <utility> instead if C++11
#include <iostream>
#define SIZE 10
using namespace std;

int main()
{

    cout<<"array values :"<<" 132, 520, 210, 510, 140 ,125,52,96,55,85"<<"\n";
    //input array values
    int array[SIZE] = { 132, 520, 210, 510, 140 ,125,52,96,55,85 };

    cout<<"sorted values : ";

    // Step through each element of the array
    for (int startIndex = 0; startIndex < SIZE; ++startIndex)
    {
        // smallestIndex is the index of the smallest element we've encountered so far.
        int smallestIndex = startIndex;

        // Look for smallest element remaining in the array (starting at startIndex+1)
        for (int nowIndex = startIndex + 1; nowIndex < SIZE; ++nowIndex)
        {
            // If the current element is smaller than our previously found smallest
            if (array[nowIndex] < array[smallestIndex])
            // This is the new smallest number for this iteration
            {
                smallestIndex = nowIndex;
            }
        }
       // Swap our start element with our smallest element
        swap(array[startIndex], array[smallestIndex]);
    }

    // Now print our sorted array as proof it works
    for (int index = 0; index < SIZE; ++index)
    {
        cout << array[index] << ' ';
    }

    cout<<"\n";
    return 0;

}

OUTPUT
