5.9 Lab 34: Numbers from a File The textbook source code chapter 5 folder contains a file named Sales.txt which contains a list of numbers. Write a program that will do the following with the file named sales.txt: open the file and if the file does not exist, it gives an error message . If the file exists, it reads the numbers from the file in a loop and calculates the following: o the count of numbers in the file, o the sum of all the numbers in the file (a running total), o the average of all the numbers in the file (perform integer division), o When all numbers have been read in, it then displays the count, the sum, and the average as shown below It closes the file when all data has been processed. Hint: Pr5-23.cpp is loaded into your template Study it and make the necessary changes When sales.txt contains the data shown in Figure 1. your program should produce the output as shown in Figure 2. Please note that the Sales.txt file attached to this assignment has different values in it than what appears in Figure 1, therefore, your program will produce different output when you run it in Develop mode. Figure 1: (Sales.txt - different values than the assignment) 1000 2000 3000 4000 5000 Figure 2: (sample output - based on Figure 1 values, not the assignment Sales.txt values) The number of elements: 5 The sum of elements: 15000 The average of elements: 3000 17/ Your Name 2 // CS 1336.exe 3 // Lab 34 4 5 // This program is Pr5-23.cpp from your textbook.
