Question 3

Pre-Defined Functions

Random

Answer 3

num = Rnd() * 10

Generates random number between 0 and 10

Question 4

Pre-Defined Functions

Round

Answer 4

num = math.round(3.14, 1)

Rounds number to 1 decimal place

Question 5

Pre-Defined Functions

Length

Answer 5

Num = len(name)

Value becomes number of letters in name variable

Question 6

Standard Algorithms

Input Validation

Answer 6

Do while num > 10
MsgBox(“Error, the number you enter should be equal to or less than 10.)
num = InputBox(“Please enter a number”)
Loop

Question 7

Standard Algorithms

Running Total

Answer 7

Total = 0
For counter = 1 to 3
Num = InputBox(“Please enter a number)
Total = Total + Num
Next

Question 8

Standard Algorithms

Traversing an Array

Answer 8

For counter = 0 to 3
MsgBox(array(counter))
Next
