Question

You are the manager of a travel agency with 20 employees. You have announced a promotional campaign for your agents to sell vacation packages. Each day you will enter the ID number of the agent (#1 - #20), the number of packages sold, and the dollar value of the package. Entries will be in a random order and the total $ value is accumulated for a 3-week period. At the end of the campaign you want a print out of those agents who sold less than $2000.00 in the 3-week time frame. You will also want a list of those that did not participate in the campaign (ones with no sales). Input and output are done using files and the eof function.

Program this in c++ pls dont copy and paste the other answer that is on here it is incorrect

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

Please note there should be input file input.txt in order to run program in same directory.
