When should one use lambda over a for statement?

Question

I know lambda is slower than a for statement so is there a reason to use it over for statements

Answer 1

Check out what you can do with a lambda:

To solve this I might have used nested for loops - it would also work. But I would have my code five-six times bigger, while I am only interested to get the result.

Answer 2

The problem that a lambda aims to solve and the one a for statement aims to solve is inherently different.

A lambda is an anonymous method, it's used to write a function inline without having to go through the trouble of writing the whole function declaration syntax.

A for statement is a loop intended to run a piece of code a specific amount of times.

A lambda could contain a for statement if you wanted it to.

Their use isn't the same so you wouldn't really have a situation where you have to decide between them.
