Ruby Code-

# takes a number and writes that number to a file then on each line

# increments from zero to the number passed

def write(aFile, number)

# You might need to fix this next line:

aFile.puts(\"number\")

index = 0

while (index

aFile.puts(number.to_s)

index += 1

end

end

# Read the data from the file and print out each line

def read(aFile)

# Defensive programming:

count = aFile.gets

if (is_numeric(count))

count = count.to_i

else

count = 0

puts \"Error: first line of file is not a number\"

end

index = 0

while (count

line = aFile.gets

puts \"Line read: \" + line

end

end

# Write data to a file then read it in and print it out

def main

aFile = File.new(\"mydata.txt\", \"w\") # open for writing

write(aFile, 10)

read(aFile)

aFile.close

end

# returns true if a string contains only digits

def is_numeric?(obj)

if /[^0-9]/.match(obj) == nil

true

end

false

end

main

Q1)

Code must follow the Ruby coding convention used in the unit (layout, and use of case).

You are storing and working with multiple values in an array.

The code must run and you must capture a screenshot that shows it working in accordance with the requirements as described here.
