Then assign your favorite song to mySong and a favorite song for friendsSong.

Display myName, friendsName, mySong, and friendsSong in statictext1 through statictext 4.

Don't forget to Dim the variables

Exercise 2:

Calculate the average grade of three test scores.

Given the following variable names how would you solve this problem in REALBasic code:

test1, test2, test2 and avgTestScore

test1 = 80

test2 = 90

test3 = 65

//in code how would you calculate the the average test score and

//display it's value in a statictext field

// in REALbasic is a comment - non-executable code

Don't forget to Dim the variables

Exercise 3:

First on a piece of paper answer the following Questions:

What is the value of grades - if studentName = “Jerry”

What is the value of grades if studentName = "Harry"

 

Dim studentName as String

Dim grades, gradesTom, gradesJerry, gradesHarry as Integer

grades = 0
gradesTom = 80
gradesJerry = 100
gradesHarry = 50

if (studentName = “Tom”) then

grades = gradesTom

elseif (studentName = "Jerry") then

grades = gradesJerry

else

grades = gradesHarry

end if

StaticText1.text = str(grades)
