What's the best way to do a backwards loop in C/C#/C++?

Question

I need to move backwards through an array, so I have code like this:

for (int i = myArray.Length - 1; i >= 0; i--)
{
    // Do something
    myArray[i] =          


        

Answer 1

I'm going to try answering my own question here, but I don't really like this, either:

for (int i = 0; i < myArray.Length; i++)
{
    int iBackwards = myArray.Length - 1 - i; // ugh
    myArray[iBackwards] = 666;
}
