Stock Transaction

Objectives:

Practice basic data types, expressions, and I/O.

On June 6 Joe purchased some stock in ABC Corp. On June 13 Joe sold all shares of the stock he purchased one week ago. There was no accrued dividend during the period.

Write aprogram to display the following information:

The amount of money Joe paid to buy the stock.

The amount of commission Joe paid to his broker when he bought the stock.

The amount of money that Joe sold the stock for.

The amount of commission Joe paid to his broker when he sold the stock.

The net profit from the two transactions. Note that this amount could be positive or negative.

The program will prompt Joe for the number of shares, the share price (i.e., price per share) he paid on June 6, and the share price (i.e., price per share) he sold on June 13. Then the program performs calculations needed to display the desired information.

The commission Joe paid to his stockbroker is 3 percent of the amount he paid for the stock. When Joe sold the stock, he paid another commission amounting to 2 percent of the amount he received for the stock.
