Hello, I am reaally green to C++
1. I am trying to create a code that calculates and then produces a small invoice.

Input: Company Name
Input: Account Number
Input: Opening Balance
Input: Account Type:
I=invoiceReceived P=invoicePayment #endTransaction

Input: Amount Invoiced
Input: Amount Paid

If someone with experience were to see the code it would probably be easy, but I cannot say I am quite there yet.

2. My code is always resulting in a syntax error:'break' 2059. Line 114

3. I would like my code to produce an invoice displaying only the companyName, accountNum, and the endingBalance,

however it gets stuck in athe loop i constructed not allowing me to get further than I,P, or # selection.

4. There are no contents of any input files, all data can be made up on the spot.

For starters, you are missing a break at the end of your default block

...

default:
cout << "Invalid response, please try again. I, P, or # ";
cout << endl;
cin >> transactionType;
break;
}

I appreciate it Master Danny, no cigar though. When I refer to my C++ book the syntax doesn't work out that way. But, I will take advice from a helpful person over a book anyday? Any idea why i get stuck in the

while ( transactionType != '#')                                                    // enter loop
    {
    cout << "Please enter a transaction type ";
    cout << endl;
    cout << "I = invoice ";
    cout << endl;
    cout << "P = Payment ";
    cout << endl;
    cout << "# = no more transactions ";
    cout << endl;
    cout << "(I/P/#) ? ";
    cout << endl;
    cin >> transactionType;
        switch (transactionType)
