What is the average density of a woman who floats in freshwater with 3% of her volume above the surface?
Write a C++ program which takes multiple Employees information (records) as inputs from the
user and save them on a file using class. Writing in file should be done using setters. Perform
following operations on the data saved in the file:
• Read data from file
• Search an employee’s information in the file
• Count the number of employees having salary more than 50,000.

Write a C++ program which takes 5 students’ information (records) as inputs from the user and
save them on a file. Your program should have two options: writing and searching.
When a user selects writing option, you are required to take three inputs from the user: student
name (string type), student age (int type). After reading these data-items write to the file named “student.txt”. Please note: write data using append mode otherwise previous information will be lost.
Your program should have a search function. The search function should provide three options
for searching: by name, by age, or by registration number. After selection of the search option
by the user, please take input (name, age, or registration number) and search that student from the
file and display its record on the screen.
