3) Write For...Next loops that calculate the sum of the following ranges and assign their sum to a variable named intSum:
A. The first 100 numbers starting with 1
B. The even numbers beginning at 10 and ending with 50
C. The numbers 20, 30, 40, 50, and 60
12) Write a bottom-controlled Do While loop with an empty body that continues while the user enters "Yes" into the strContinue variable.
13) Write a Do While loop to validate that the user enters a nonzero integer into an input box for a variable named intDenominator.
Explanation / Answer
3) Write For...Next loops that calculate the sum of the following ranges and assign their sum to a variable named intSum:
A. The first 100 numbers starting with 1
Dim intSum as Integer = 0
For index As Integer = 1 To 100
intSum += index
Next
Console.WriteLine(intSum)
B. The even numbers beginning at 10 and ending with 50
For index As Integer = 10 To 50 Step 2
intSum += index
Next
Console.WriteLine(intSum)
C. The numbers 20, 30, 40, 50, and 60
For index As Integer = 20 To 60 Step 10
intSum += index
Next
Console.WriteLine(intSum)
12) Write a bottom-controlled Do While loop with an empty body that continues while the user enters "Yes" into the strContinue variable.
Dim strContinue as String
Do
strContinue = Console.ReadLine()
Loop Until String.Compare(strContinue, "Yes", False)
13) Write a Do While loop to validate that the user enters a nonzero integer into an input box for a variable named intDenominator.
Dim intDenominator as Integer
Do While intDenominator = 0
intDenominator = Console.ReadLine()
Loop
