The following example demonstrates dynamic loop unrolling for a simple program written in C. Unlike the assembler example above, pointer/index arithmetic is still generated by the compiler in this example because a variable (i) is still used to address the array element.
The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.

Edit time is when the source code of the program is being edited. This spans initial creation to any bug fix, refactoring, or addition of new features. Editing is typically performed by a person, but automated design tools and metaprogramming systems may also be used. Compile time is when source code is translated into machine code by a compiler.
Bootstrapping a compiler has the following advantages: [6] It is a non-trivial test of the language being compiled, and as such is a form of dogfooding.; Compiler developers and bug reporters only need to know the language being compiled.
