Exercise 6 (FizzBuzz with OO concepts)

Step 1:

Read off an INI file with the following format:

• max_int (In this case key value is) = 100
• lower_divisor (In this case key value is) = 3
• upper_divisor (In this case key value is) = 5
• lower_divisor_label (In this case key value is) = fizz
• upper_divisor_label (In this case key value is) = buzz

Step 2:

Print the integers 1-max_int, unless...

• If the integer is divisible by lower_divisor, print lower_divisor_label instead of the integer.
• If the integer is divisible by upper_divisor, print upper_divisor_label instead.
• If it is divisible by both lower_divisor and upper_divisor, print lower_divisor_label+upper_divisor_label.

Step 3:

In addition to printing the output, store it in a log file named log_.text
