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 $1000.00 in the 3 week time frame. You will also want a list of those that did not participate in the campaign. Input and output are done using files.
