Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Binus’s Used Cars, Inc. employs several salespeople. Mr. Robert, the owner of the company, has provided a file that contains sales records for each salesperson for the past month. Each record in the file contains the following two fields: The salesperson’s ID number, as an integer The amount of a sale, as a real number The records are already sorted by salesperson ID. Brewster wants you to design a program that prints a sales report. The report should show each salesperson’s sales and the total sales for that salesperson. The report should also show the total sales for all salespeople for the month. Here is an example of how the sales report should appear:

"In the student sample program files for this chapter, you will find a text file named house_prices.csv. The file contains the following data about houses for sale in a city: Price Number of bedrooms Number of bathrooms Square feet of living space The data stored in each line is formatted in the following way: Price,Bedrooms,Bathrooms,SquareFeet Notice that the data items are separated by commas. The first line in the file looks like this: 221900,3,1,1180 The data stored in this line is: Price = $221,900 Bedrooms = 3 Bathrooms = 1 Square feet = 1,180 Design a class that has properties for the four pieces of data. In an application, read the file and store each house’s data in an instance of the class. The class instances should be stored in a List.

USING C++ PLEASE CREATE THREE FILES! IntCollection.h (or IntCollection.hpp): class definition IntCollection.cpp: class implementation main.cpp, including sample output and your answer to question 6 at the bottom. : main program to run the code The following code creates an IntCollection object named ‘c’. It adds seven integers to ‘c’, then uses a for loop to display the seven integers: int main() { IntCollection c; c.add(45); c.add(-210); c.add(77); c.add(2); c.add(-21); c.add(42); c.add(7); for (int i = 0; i < c.getSize(); i++) { cout << c.get(i) << endl; } } For this assignment you will add a copy constructor, a destructor, and three overloaded operators to the IntCollection class. In the design diagram below, the black member functions represent code that has already been implemented. You will be implementing the green items. Each item that you will be adding to the class is described below the diagram. private: int size // the number of ints currently stored in…

JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…
Create a C++ Program to do the following: Create a .txt file with up to 10 double numbers. Then in your code, create an array to hold 10 doubles. Openthe file. Read each number from the file into a place in the array. Count how many numbers you read. Close thefile.Now, go through the data in the array twice. Don’t go through all 10 elements in the array, only the elementsfor which you have read data. On the first pass, calculate the average of the numbers in the array. (Calculate thetotal, divide by count, that is µ).On the second pass through the data, for each number you should calculate how far it is from the average(number - average), square that, and keep a sum of the squares, that is S.When you’re done, calculate the average of that sum of squares, A. The square root of that number, σ is yourstandard deviation.Print out the average µ and standard deviation σ
