Control flow

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 provides conditional execution of statements.
• Loops:
  • while executes the loop body for as long as the loop expression returns True.
  • for iterates over an object, such as elements in an array.
  • break exits loops.
  • continue goes to the next iteration of a loop.
• return ends the flow of execution within a function, returning it to the caller.
