You Are Hired!

What is mathematical model?

====

Coding standards:

- { goes on the same line as condition

- Code indented 4 spaces

- } goes on a new line

You are hired by Megan Investment Bank to create an investment software to calculate a total return with the following input parameters:

1. Initial Investment

2. Number of day invest

3. Return per day

totalReturn = numberOfDayInvest * returnPerDay - initialInvestment

Your software recommends the following:

1. If totalReturn is > to initialInvestment and numberOfDayInvest < 4

Print "Good Investment"

Print "Your total return is: $"

2. If totalReturn is < initialInvestment and numberOfDayInvest = < 4

Print "Bad Investment"

Print "Your total return is: $"

====

- for-in: when you know how many times loop run

for number in 1...4 {

print("My name is Megan")

print(number)

print("And the value is \(number) \n")

}

- 1...4 : Closed range (each time it goes thru we say it iterates and each cycle is iteration)

- ... is Closed range operator

- \n a new line

- for-in with array:

let kidsInClass = ["Natalie", "Megan", "Stephanie", "Joleen", "Ashton", "Nhi", "Bao"]

for kidsName in kidsInClass {

print("Good morning \(kidsName)")

//print("Good morning \(kidsInClass)")

}

Homework:

Write a program say hi to all your friends in the class 3 times using nested for-in loop

- Review array, operators, if and case conditional statements

- Study the for-in and vocabulary (i.e.. iteration, iterates, cycle)
