如何查找数组中第二大值的索引

Given this:

鉴于这种：

int areas[20];

for (int i = 0; i < 20; i++)
{
    areas[i] = detectedBlobs[i].getWidth() * detectedBlobs[i].getHeight();
}

I understand how to sort arrays and find the first, second, third, etc. largest values, but how can I find the index values associated with the first, second or third largest values?

我理解如何对数组进行排序并找到第一个，第二个，第三个等最大值，但是如何找到与第一个，第二个或第三个最大值相关联的索引值？

As you already know how to find the largest value in a sorted array, the next step would be enumerate through unsorted array and compare each object with largest value if matches you can get the index of it! –

正如您已经知道如何在排序数组中找到最大值，下一步将通过未排序数组进行枚举，并将每个对象与最大值进行比较，如果匹配则可以得到它的索引！ -
