Answer to Question #213478 in C++ for Safrina

Question

Due to lockdown, AB bank handles a limited number of customers each day (30 persons). To maintain social distance, these persons enter into the bank in 3 rounds. First, 10 people go and perform their task one after one. After 2 minutes, one of them leave the bank finishing their work. When all of the 10 persons leave the bank, 10 more people enter into the bank and perform their work. This continues until all the 30 people are served. 

Write a program that automates this task. It will store the name of the customers who are entering the bank. When the quota of 10 persons gets filled up, it will prevent others from entering the bank. After each 2 minutes, the program will print the name of the customer who is about to leave the bank. When the bank will be empty, it will let 10 more people enter into the bank. After serving 30 people, it will announce that bank is closed for the day
