Chapter 3: Expressions and Control Flow Structures
With a foundation in variables and data types, we now turn to how programs perform operations and make decisions. This chapter covers expressions, the way Julia combines values and operators to produce new values, and control flow structures, which dictate the order in which statements are executed.
You will learn to:
- Formulate expressions using arithmetic, comparison (e.g.,
$x > y$), and logical operators. - Implement conditional execution paths with
if,elseif, andelsestatements. - Create loops for repetitive tasks using
forandwhileconstructs. - Manage loop behavior with
breakandcontinue, and write concise conditionals with the ternary operator.
Upon completing this chapter, you will be able to construct programs that can evaluate conditions, perform varied calculations, and automate repetitive processes.
