I wrote the following program for buying and selling stock, and also displaying a record of these transactions. I am using command line entry. I am using exceptions to be able to display an error message that either a negative price or negative number of stocks whenever a stock is either bought or sold. Afterwards, it does not record the transaction, and instead asks the user to enter another command. Afterwards, it will let me buy or sell another stock, however, afterwards, if I again try to display the list of transactions, it displays them, however, afterwards kicks me out of the program. I am not sure why. Can you please help me debug. Many thanks.

To begin the execution of the program, at the command line, I enter the following:

"TransactStock transactions$1",$ where TransactStock is the name of the program, and transactions$1$ is the name of the text file that has a list of $4$ buy or sell stocks that are first imported into the program, and then the user can manually buy or sell other stocks, to add to the transaction list.

Here is the text in the transactions$1$ text file:

$1100$ INTC $30\mathrm{.}13$

$2200$ CSCO $24\mathrm{.}00$

$150$ IBM $130\mathrm{.}00$

$2100$ AAPL $94\mathrm{.}28$

$...$where $1=$ buy, $2=$ sell

the $2$nd number is the number of shares

the $3$rd entry is the stock code

the last number is the share price

Attached are only snippets of the exception code parts of my "TransactStock" program. I was unable to import the entire code.
