Hi can someone plaese help create a C++ program for this thanks

Figure 2.9 shows the problem specification and IPO chart for the Addison O'Reilly problem. Notice that each instruction in the algorithm starts with a verb: enter, calculate, and display. The algorithm begins by entering the input items. It then uses the input items to calculate the output item. An algorithm should state both what is to be calculated and how to calculate it. In this case, the cost is calculated by multiplying the sale price by the sales tax rate and then adding the result to the sale price. The last instruction in the algorithm displays the output item. To avoid confusion, it is important that the algrithm is consistent when referring to the input and output items. For example, if the input item is listed as sales tax rate, then the algorithm should refer to the item as sales tax rate rather than a different name, such as tax nate or mate. Problem specification
