Module Example
Public Sub Main()
' Get population data for New York City, 1960-2000.
Dim population = Tuple.Create(
"New York", 7781984, 7894862, 7071639, 7322564, 8008278)
Dim rate = ComputePopulationChange(population)
' Display results.
Console.WriteLine("Population Change, {0}, 1960-2000", population.Item1)
Console.WriteLine()
Console.WriteLine("Year {0,10} {1,9}", "Population", "Annual Rate")
Console.WriteLine("1960 {0,10:N0} {1,11}", population.Item2, "NA")
Console.WriteLine("1970 {0,10:N0} {1,11:P2}", population.Item3, rate.Item2/10)
Console.WriteLine("1980 {0,10:N0} {1,11:P2}", population.Item4, rate.Item3/10)
Console.WriteLine("1990 {0,10:N0} {1,11:P2}", population.Item5, rate.Item4/10)
Console.WriteLine("2000 {0,10:N0} {1,11:P2}", population.Item6, rate.Item5/10)
Console.WriteLine("1960-2000 {0,10:N0} {1,11:P2}", "", rate.Item6/50)
End Sub
' Compute rate of population change by decade and overall.
Private Function ComputePopulationChange(data As Tuple(Of String, Integer, Integer, Integer, Integer, Integer)) _
As Tuple(Of String, Double, Double, Double, Double, Double)
Dim rate = Tuple.Create(data.Item1,
(data.Item3 - data.Item2)/data.Item2,

Return rate
