/* TempAgency.cs
* This application is used by a temporary work agency to
* set projections for sales for new hires. The program enables the
* user to input salesmen's names and expected sales goals.
* The sales figure is placed in a two-dimensional array
* and expected sales figures for four months are added.
* These projections are based on increasing sales at
* least 5% each month over the four-month period.
* for testing purposes, four salesmen data are entered.
