Justify your answer with valid reason in either case.
Senerio:
ATM (Automated Teller Machine) machines are electronic outlets that allow customers to do their basic transactions without interaction of bank’s representative. While programming this ATM in C++, We have created a class named CUSTOMER which stores customer data (i.e. name, NIC, age, address, account balance and transaction history etc.). There is a friend function that wants to access some private information of the class.
Question:
Being a C++ developer, analyze the whole scenario, what do you think, does a friend function contradict the rules of Encapsulation?

Faisalabad Electric Supply Company (FESCO) distributes and supplies electricity to about 4.50 million customers within its territory with a population over 26 million under a distribution license granted by National Electric Power Regulatory Authority (NEPRA). The main determinant of electricity bill in Pakistan is the number of units consumed. Usually, electricity companies charge different prices as per kilowatt hour (kWh) to residential users, small commercial users and industrial companies etc according to the units consumed. For example, the approximate schedule of electricity tariffs for residential users is 5.79 Rs/kWh for 001-100 units, 8.11 Rs/kWh for 101-200 units, 10.20 Rs/kWh for 201-300 units, 17.60 Rs/kWh for 301-700 units, and 20.70 Rs/kWh for above 700 units. For commercial users, the approximate schedule of electricity tariffs is 18 Rs/kWh for sanctioned load less than 5 kW and 19.68 Rs/kWh for sanctioned load 5 kW and above. Similarly, for industrial users, the schedule of electricity charges is different. Being a student of managerial economics, analyze the above case study carefully and identify which type of price discrimination is discussed in above case study. Also discuss the reason logically.
