Runtime vs. Compile time

Question

What is the difference between run-time and compile-time?

Answer 1

Compile Time:

Things that are done at compile time incur (almost) no cost when the resulting program is run, but might incur a large cost when you build the program. Run-Time:

More or less the exact opposite. Little cost when you build, more cost when the program is run.

From the other side; If something is done at compile time, it runs only on your machine and if something is run-time, it run on your users machine.
