Chapter 3.2, Problem 21E

Explanation of Solution

Given: The following lines of code with a list box:

Dim a As Integer = 4

Dim b As Integer = 2

Dim c As String = "Municipality"

Dim d As String = "pal"

lstBox.Items.Add(c.Length)

lstBox.Items.Add(c.ToUpper)

lstBox.Items.Add(c.Substring(a, b) & c.Substring(5 * b))

lstBox.Items.Add(c.IndexOf(d))

To find: The output of the lines of code that are displayed in the text box or list box.

Dim a As Integer = 4

Dim b As Integer = 2

Dim c As String = "Municipality"

Dim d As String = "pal"

lstBox.Items.Add(c.Length)

lstBox.Items.Add(c.ToUpper)

lstBox.Items.Add(c.Substring(a, b) & c.Substring(5 * b))

lstBox.Items.Add(c.IndexOf(d))

Solution:

In the aforementioned lines of code, the integer type variables, a and b, are declared and initialized to 4 and 2, respectively whereas the string type variables, c and d, are declared and initialized to “Muncipality� and “pal�, respectively...
