Why is my first set of numbers on the closed parenthesis stuck on 21?

I want the output to have the numbers on the first set to go from 0-20 and the second set to 0-100 but not 0,1,2,3,4,5 but 0,5,10 basically skipping each 5. Here's a screenshot of my code and output.

Solution

  • A couple options for you...

    Option 1:

    For a As Integer = 0 To 20
    Dim b As Integer = a * 5
    Console.WriteLine("index number:({0}) = {1}", a, b)
Next

    Option 2:

    Dim b As Integer = 0
For a As Integer = 0 To 20
    Console.WriteLine("index number:({0}) = {1}", a, b)
    b = b + 5
Next

    Option 3:

    Dim a As Integer = 0
Dim b As Integer = 0
While a <= 20
    Console.WriteLine("index number:({0}) = {1}", a, b)
    a = a + 1
    b = b + 5
End While

    In C#, you could do:

    for(int a=0,b=0; a<=20; a++,b+=5) {
  Console.WriteLine("index number:({0}) = {1}", a, b);
}
