How to replace for-loops with a functional statement in C#?

Question

A colleague once said that God is killing a kitten every time I write a for-loop.

When asked how to avoid for-loops, his answer was to use a functional language. However

Answer 1

For loops don't kill people (or kittens, or puppies, or tribbles). People kill people. For loops, in and of themselves, are not bad. However, like anything else, it's how you use them that can be bad.
