In this lesson, you will learn: Various decision structures used in all computer programming languages if decision structures Multiple decision structures such as if…else and switch/Select Case Reading flowcharts Decision tables Evaluating expressions

5. break

6. case

7. Algorithm

8. Compound statement

9. Nested statements

11. Understand computer decision structures Relational Expressions A relational operator is used to compare two values, resulting in a relational expression. For example: number > 16 grade == ‘F’ passing >= 60 A list of relational operators: < less than > greater than <= less than or equal to >= greater than or equal to == equal to != not equal to

12. Understand computer decision structures Logical Operators && and || or ! not

13. Understand computer decision structures if-else Statement: if (condition) { statement1; } else { statement2; }

14. Understand computer decision structures if-else if Statement: if (condition1) { statement1; } else if (condition2) { statement2; } else { statement3; }

15. Understand computer decision structures switch Statement: intcaseSwitch = 1; switch (caseSwitch) { case 1: Console.WriteLine("Case 1"); break; case 2: Console.WriteLine("Case 2"); break; default: Console.WriteLine("Default case"); break; }

16. Understand computer decision structures Decision Table A concise way of demonstrating logic Creates an association between conditions and actions to execute

17. Assignment 1 boolisFun = F; boolisKind = F; boolisPopular = T; if isFun && isKind || isPopular; Console.WriteLine("You are my friend."); else Console.WriteLine("Who are you?");

18. Answer 1 boolisFun = false; boolisKind = false; boolisPopular = true; if (isFun && isKind || isPopular) Console.WriteLine("You are my friend."); else Console.WriteLine("Who are you?");
