sort an array of floats in c++

Question

I have an array of (4) floating point numbers and need to sort the array in descending order. I'm quite new to c++, and was wondering what would be the best way to do this?

Thanks.

Use std::sort with a non-default comparator:

float data[SIZE];
data[0] = ...;
...

std::sort(data, data + size, std::greater<float>());
