How to convert basic data to user defined data type?

There is a secret organization and they

want to create a secret language for the

calculation to make the data secure.

Now the manager of the organization

asked his IT employee to make the

program which will function as follows:

a) * will subtract the numbers b) - will

divide the numbers c) / will add the

Use operator overloading.

Write a program that calculates the take-home pay for an employee. The two types of employees are salaried and hourly. Allow the user to input the employee first and last name, id, and type. If an employee is salaried, allow the user to input the salary amount. If an employee is hourly, allow the user to input the hourly rate and the number of hours clocked for the week. For hourly employees, overtime is paid for hours over 40 at a rate of 1.5 of the base rate. For all employees’ take home pay, federal tax of 18% is deducted. A retirement contribution of 10% and a Social Security tax rate of 6% should also be deducted. Use appropriate constants. Design an object-oriented solution. Create a second class to test your design.

A college offers a course that prepares students for the state licensing exam for real estate brokers. Last year, ten of the students who completed this course took the exam. The college wants to know how well its students did on the exam. You have been asked to write a program to summarize the results. You have been given a list of these 10 students. Next to each name is written a 1 if the student passed the exam or a 2 if the student failed. Your program should analyze the results of the exam as follows: Input each test result (i.e., a 1 or a 2). Display the prompting message "Enter result" each time the program requests another test result. Count the number of test results of each type. Display a summary of the test results indicating the number of students who passed and the number who failed. If more than eight students passed the exam, print the message "Raise tuition."

Write a C++ program to find the table of numbers using a while loop. Your program should ask the size of the table. That size defines the rows and columns.

Explain how overloading a unary operator is almost similar to overloading a binary operator with necessary examples and include main() function to demonstrate. Mention the differences between these two in terms of number of operands they deal with.

A customer opens an account at a bank with an initial amount. The account number, name, and balance of the customer are generated. The customer can deposit money and withdraw money as per need, this will modify the existing account balance. It should also be checked if the demanded amount is available during withdrawal. The customer can also close the account, the available amount will be paid out. Write a programme to input and display data for 5 customers with the use of Constructor and Destructor

Make a file by yourself named ”Integer.txt” and add 5 integer values in it. Now, write a C++ program that reads data (5 integers) from the file and store them in integer array. Also make another integer array (int result []) of same size to store the results. The program should check for each number in array if it is prime number or not. If the number is prime, update value in result[] array from 0 to 1. Lastly, write output in another file named “Result.txt”
