// Each time a salesperson sells a car at the Pardeeville New and Used Auto Dealership,
// a record is created containing the salesperson’s name and the amount of the sale.
// Sales of new and used cars are kept in separate files because several reports
// are created for one type of sale or the other. However, management has requested
// a merged file so that all of a salesperson’s sales, whether the vehicle was new or used,
// are displayed together. The following code is intended to merge the files

If you can explain this to me that I can understand how to do it?
Under the detailLoop() Statements
In Else Part you have used wrong logic
it should be like below
else
output newSalesperson, newAmount to allSales
input newSalesperson, newAmount from newSales
Thank you syed!!
This code is intended to merge two files, "NewSales.dat" and "UsedSales.dat", that contain records of sales made by salespeople at the Pardeeville New and Used Auto Dealership. The merged file, "AllSales.dat", will contain all the sales made by each salesperson, whether the vehicle was new or used.
Let's break down the code and understand each step:
1. Declare variables: The code declares variables to store the salesperson's name and the amount of the sale for both new and used cars. It also declares a variable "bothAtEof" to track whether both files have reached the end. "HIGH_NAME" is a constant used for comparison. Lastly, the code declares input and output file objects for the new sales file, used sales file, and the merged file.
2. Start the main program: The main program starts by calling the "getReady()" subroutine.
3. "getReady()" Subroutine:
a. Open input files: The code opens the new sales file ("NewSales.dat") and the used sales file ("UsedSales.dat").
b. Open output file: The code opens the merged file ("AllSales.dat").
c. Read from the new sales file: The code reads the salesperson's name and the amount of the sale from the new sales file. If the file has reached the end, it assigns the "HIGH_NAME" to the salesperson's name variable.
d. Read from the used sales file: The code reads the salesperson's name and the amount of the sale from the used sales file. If the file has reached the end, it assigns the value of salesperson's name from the new sales file to the salesperson's name variable for used sales.
e. Check for end of both files: If both new sales and used sales files have reached the end, the "bothAtEof" variable is set to "Y" to indicate that both files have been processed.
4. Start a loop: The main program enters a loop that continues until both files have reached the end.
5. "detailLoop()" Subroutine:
a. Compare salesperson IDs: The code compares the salesperson's name from the new sales file with the salesperson's name from the used sales file. If the salesperson's name from the new sales file is greater than the salesperson's name from the used sales file, it means that it's time to output a record from the used sales file to the merged file. Otherwise, it's time to output a record from the new sales file to the merged file.
b. Output record: The code outputs the salesperson's name and the amount of the sale to the merged file.
c. Read from the used sales file: The code reads the salesperson's name and the amount of the sale from the used sales file. If the file has reached the end, it assigns the "HIGH_NAME" to the salesperson's name variable for used sales.
d. Read from the new sales file: The code reads the salesperson's name and the amount of the sale from the new sales file. If the file has reached the end, it assigns the value of salesperson's name from the used sales file to the salesperson's name variable for new sales.
e. Check for end of both files: If both new sales and used sales files have reached the end, the "bothAtEof" variable is set to "Y" to indicate that both files have been processed.
6. Finish the program: The main program closes the input and output files and then returns.
I hope this helps you understand the code better!
This code is a program that merges two files containing sales records from a car dealership. The files are sorted by salesperson ID number. The goal is to create a merged file that combines the sales records from both the new and used car files.
Here's an explanation of how the program works:
1. The program starts with the "start" keyword, indicating the beginning of the main program.
2. The program declares several variables: newSalesperson (string), newAmount (number), usedSalesperson (string), usedAmount (number), bothAtEof (string), HIGH_NAME (string), newSales (input file), usedSales (input file), and allSales (output file). These variables will be used to store and manipulate the sales data.
3. The program calls the "getReady()" function. This function is responsible for initializing the input and output files, as well as reading the first sales records from the new and used car files.
4. Inside the "getReady()" function, the program opens the "NewSales.dat" file and assigns it to the "newSales" variable. It also opens the "UsedSales.dat" file and assigns it to the "usedSales" variable. Additionally, it opens the "AllSales.dat" file and assigns it to the "allSales" variable.
5. Next, the program reads the "newSalesperson" and "newAmount" values from the "newSales" file. If the end of the file (EOF) is reached, it means there are no more records in the file, so the program sets the "newSalesperson" value to "HIGH_NAME" (which represents a high value that will not match any salesperson ID).
6. The program then reads the "usedSalesperson" and "usedAmount" values from the "usedSales" file. Again, if the end of the file is reached, the program sets the "usedSalesperson" value to "newSalesperson" (which represents that the used car sales file has reached its end).
7. The program checks if both "newSalesperson" and "usedSalesperson" have been set to "HIGH_NAME", indicating that both files have reached the end. If this is the case, the program sets the "bothAtEof" variable to "Y" to indicate that both files are at the end.
8. The program then returns to the main program and enters a loop using the "while" keyword and the condition "bothAtEof = "Y"". This loop will keep executing until both files have reached the end.
9. Inside the loop, the program calls the "detailLoop()" function. This function is responsible for merging the sales records from the two files.
10. Inside the "detailLoop()" function, the program compares the values of "newSalesperson" and "usedSalesperson". If the value of "newSalesperson" is greater than "usedSalesperson", it means that the next sales record in the used car file has a higher salesperson ID. In this case, the program outputs the "usedSalesperson" and "usedAmount" values to the "allSales" file, and then reads the next sales record from the used car file.
11. If the value of "newSalesperson" is not greater than "usedSalesperson", it means that the next sales record in the new car file has a lower or equal salesperson ID. In this case, the program outputs the "newSalesperson" and "newAmount" values to the "allSales" file, and then reads the next sales record from the new car file.
12. After outputting the sales record, the program checks if either of the files has reached the end (EOF) by comparing "newSalesperson" and "usedSalesperson" to "HIGH_NAME". If both are set to "HIGH_NAME", it means that both files have reached the end, so the program sets the "bothAtEof" variable to "Y" to indicate this.
13. The program then returns to the main program, where the loop condition is checked again. If "bothAtEof" is still "Y", the program exits the loop and moves on to the "finish()" function.
14. Inside the "finish()" function, the program closes all the input and output files.
15. Finally, the program returns to the main program and stops.
To use this program, you would need to have three files: "NewSales.dat", "UsedSales.dat", and "AllSales.dat". The "NewSales.dat" and "UsedSales.dat" files should contain the sales records sorted by salesperson ID number. After running the program, the "AllSales.dat" file will be created, containing the merged sales records.
