week 5 CPSC-411 Mobile Device Application Programming - Control Flow and Enumerations

These flashcards cover key vocabulary related to control flow and enumerations in Swift programming.

for-in loop

A control flow statement used to iterate over sequences such as arrays, dictionaries, or ranges.

while loop

A control structure that repeatedly executes a block of code as long as a specified condition is true.

repeat-while loop

A variant of the while loop that executes the block of code at least once before checking the condition.

if statement

A conditional statement that executes a block of code only if a specified condition is true.

switch statement

A control flow statement that evaluates a value and compares it against multiple patterns, executing the corresponding block of code.

continue statement

A control transfer statement that tells a loop to skip the current iteration and start the next.

break statement

A control transfer statement that terminates the execution of the current control flow statement.

Control Transfer Statements

Statements that change the order of execution in your code.

enum

A data type that defines a common type for a group of related values, allowing type-safe usage within the code.

associated values

Values that allow enumeration cases to store additional information of any type.

CaseIterable

A protocol that enables an enumeration to expose a collection of all its cases.

CaseIterable

A protocol that enables an enumeration to expose a collection of all its cases.

guard statement

A control flow statement in Swift that ensures a condition is true, or exits the current scope if false, providing an early exit.

Raw Values (enums)

Pre-populated values of a specific type (e.g., Int, String) that can be assigned to each case of an enumeration.

Labeled Statements

A way to give a loop or conditional statement a human-readable label, allowing break or continue statements to exit or skip specific outer control flow statements.

default case (switch)

A required case in a switch statement that matches any value not already handled by other cases, ensuring exhaustive pattern matching.
