#  This example program loads a file (sample.csv)
#  that contains this content:
# 
#  year,color,country,food
#  2001,red,France,cheese
#  2005,blue,"United States",hamburger
#  2008,green,Italy,pasta
#  1998,orange,Japan,sushi
# 
#  The first row contains the column names.
#  This file is available at:
#  http://www.chilkatsoft.com/testData/sample.csv

csv = Chilkat::CkCsv.new()

#  Prior to loading the CSV file, indicate that the 1st row
#  should be treated as column names:
csv.put_HasColumnNames(true)

#  Load the CSV records from the file:

success = csv.LoadFile("sample.csv")
if (success != true)
    print csv.lastErrorText() + "\n"
    exit
end

#  Display the contents of the 3rd column (i.e. the country names)

n = csv.get_NumRows()
for row in 0 .. n - 1
    print csv.getCell(row,2) + "\n";
end
