Consider the following C++ program that performs the following activities:

1. Opens a .csv file (path supplied through command line argument) that contains details of the ECE2071 final project demonstration conducted by student teams. In order to ensure that Project Team IDs are redacted in the file, the team that refers to a particular line in the file is identified through the combination of STM 32 Nucleo kits used during the demonstration. Thus, each line of the file stores the unique IDs of STM32 boards utilised and audio processing parameters achieved by a particular team during the demonstration in the following format:
   sampling_STM_serial_number, processing_STM_serial_number, sampling_rate (sps), bits_per_sample, duration (in seconds)

   The first few lines of the .csv file are shown below.

   025,057,22050,16,25

   016,087,10000,8,25

   001,004,44100,16,60

   015,022,05000,16,45

2. Stores the details in the input file into a map container to ensure that duplicate entries for a particular team are avoided during the grading process.
3. Writes the details in the map to an output file (path again supplied through command line argument) that will be utilized by the unit coordination team during the grading.

Answer the following questions:

1. What is the significance of this-> pointer utilized in the program? (2 marks)
2. What is the significance of the address operator (&) on Line 44 in the program? (2 marks)
3. How does the map container deal with a duplicate entry in the input file? (2 marks)
4. Describe the activities performed in Lines 31-34 of the program. (2 marks)
5. Describe the format of information in the output file. Is the order of teams in the input and output files similar? If yes, why? If no, explain why the order is different. (2 marks)
6. Explain how the map container utilizes the information stored in the elements of the vector container in the program. (2 marks)
