Question

Problem Statement

Last month Tian purchased some stock in Acme Software, Inc. Here are the details of the purchase:

 The number of shares that Tian purchased was 1,000

 When Tian purchased the stock, he paid $33.92 per share

 Tian paid his stockbroker a commission that amounted to 2% of the amount he paid for

the stock.

One week later, Tian sold the stock. Here are the details of the sale:

The number of shares sold was 1,000
He sold the stock for $36.78 per share
He paid his stockbroker another commission that amounted to 2% of the amount he received for the stock.

Please write a program that displays the following information:

 The amount of money Tian paid for the stock.

 The amount of commission Tian paid his broker when he bought the stock.

 The amount that Tian sold the stock for.

 The amount of commission Tian paid his broker when he sold the stock

 Display the amount of profit that Tian made after selling his stock and paying the two

commissions to his broker (If the amount of profit that your program displays is a negative number , then Tian lost money on the transaction)

This what i have done. Please if you have any suggestion to make it perfect.
