## Overview
|
|
|
|
Blocks of statements are generally executed linearly. However, statements are
|
|
the primary place where this flow of execution can be controlled.
|
|
|
|
Carbon's flow control statements are:
|
|
|
|
- [`if` and `else`](conditionals.md) provides conditional execution of
|
|
statements.
|
|
- Loops:
|
|
- [`while`](loops.md#while) executes the loop body for as long as the loop
|
|
expression returns `True`.
|
|
- [`for`](loops.md#for) iterates over an object, such as elements in an
|
|
array.
|
|
- [`break`](loops.md#break) exits loops.
|
|
- [`continue`](loops.md#continue) goes to the next iteration of a loop.
|
|
- [`return`](return.md) ends the flow of execution within a function,
|
|
returning it to the caller.
