Question

Description:

In this assignment, you will write a program in C++ that uses files and nested loops to create a file for real estate agents home sales and then read the sales from the file and calculates the average sale for each agent. Each agent sold 4 homes.  Use a nested loop to write each agent’s sales to a file. Then read the data from the file in order to display the agent’s average sale and the average for all sales. Determine which agent had the highest total sales and display their name and total sales

Enter 4 sales for each agent. Column 1 is the agent’s name and Column 2-5 are their sales in 1000’s.

Agent	House 1	House 2	House 3	House 4
Martha	90	125	60	125
Leela	55	25	75	100
Jorge	130	60	70	100

 

Requirements:

1.      Use a nested loop structure to input the data and write the data to a text file.

a.      The outer loop will be a while loop (unknown number of agents), the inner loop will be a for loop (4 sales).

b.      Have the user enter the agent’s name.

c.      Have the user enter 4 sales and validate whether the sale prices are in range (0-200).

d.      Since you do not know how many agents will be entered, add a way to quit the loop.

e.      Add a new line (endl) after each agent name. Add spaces after each sales added to the text file except after the last sale add a new line.

f.       You may not count the number of agents processed.

 

 

2.      Use a nested loop structure to read the data from the text file and calculate the agent’s average sale.

a.      The outer look will be a while loop; the inner loop will be a for loop (4 sales)

b.      To calculate each agent’s average sale, use an accumulator (total agent variable) initialized to 0 before the for loop, then calculate the agent’s average after the loop.

c.      To calculate the total average sale, you will need an accumulator for the company.  Add each agent’s total into the total agency variable following the for loop, then calculate the agency average after the while loop.

d.      Only display 2 decimals for the averages.

3.      Use cout to output the values of the variables to the console. Your cout statement MUST use the variables to display the values

4.      Output must be labelled and easy to read as shown in the sample output below.

5.      Program must be documented with the following:

a.      // Name

b.      // Date

c.      // Program Name
