Answer to Question #322601 in C++ for 11111

Question

A company wants you to write a C++ program to maintain the contact details of its employees. Employee has a name, email, phone number, education, address, office phone extension, room number. The number of employees in the company are 21 but the program should be scalable to handle more employees. The company admin will use this system and he should be able to add, update, delete, search, print individual employee record and to print list of all employees.

Your task is to tell me that how would you do that, by using algorithm (psedocode or flow chart).
