    <p>hey guys im writing a loan program here using two classes. I declare an object from my "MortCalc" Class in My LoanOfficer Class. The loan officer class is to determine whether a user qualifies for a loan or not a user enters the principal of a loan, monthly income, and monthly expenses. The Loan officer class then does a calculation and reports back to the user if the loan was approved using one rule. The rule is this: if the monthly payment of the loan( which is obtained from my MortCalc Class) and monthly expenses total is greater than 50% of the monthly income then the loan is not approved. The problem I've encountered is with calculating this. I try to store the calculation in a "rule" variable but it always equals 100 thus never approving the loan! obviously im doing something wrong here but i can't figure out what. here is my code:</p> <p><strong>LoanOfficer.h</strong> </p> <pre><code>class LoanOfficer { //private class variables private: MortCalc mc; double intRate; double monthlyIncome; double term; double monExpenses, principal; double rule; bool bLoanApprove, bOpen; string userName, fileName,lenderName; string loanOfficer, Welcome; int counter; void calculate(); </code></pre> <p><strong>LoanOfficer.cpp</strong></p> <pre><code>LoanOfficer::LoanOfficer() { //initializing variables; intRate = 4.1; term = 30; counter=1; principal=0; lenderName="John's Bank"; Welcome =""; calculate(); } void LoanOfficer::calculate() { rule = ((mc.GetMonPymt() + monExpenses) / monthlyIncome)* 100; //i have a getter in my Mortcalc class which get's the monthly Payment. } bool LoanOfficer::isApproved() { if(rule&gt;50) { bLoanApprove = true; } else{ bLoanApprove = false; } return bLoanApprove; } string LoanOfficer::getApproval() { if(bLoanApprove==true) { stringstream ss; ss&lt;&lt;"\n\nLoan Approval Status: Yes" &lt;&lt;"\nLoan amount: " &lt;&lt;principal &lt;&lt;"\nInterest Rate: " &lt;&lt;intRate &lt;&lt;"\nMonthly Payment: " &lt;&lt;monPayment &lt;&lt;"\nTotalLoan: " &lt;&lt;mc.GetTotalLoan() &lt;&lt;"\nTotal Interest" &lt;&lt;mc.GetTotalInt() &lt;&lt;"\n\nCongratulations We're looking to do business with you " &lt;&lt;userName&lt;&lt;"!"; loanOfficer = ss.str(); } else { stringstream ss; ss&lt;&lt;"\n\nLoan Approval Status: No" &lt;&lt;"\n\n Income vs Montly Payment and expenses does not meet " &lt;&lt;"\n the 50% criteria net income that is necessary for this" &lt;&lt;"\n institution to approve this loan"; loanOfficer = ss.str(); } return loanOfficer; } void LoanOfficer::setPrincipal(double p) { mc.setPrin(p); principal = p; } bool LoanOfficer::isOpen() { return bOpen; } void LoanOfficer::setMonInc(double mi) { monthlyIncome = mi; } void LoanOfficer::setExpenses(double ex) { monExpenses = ex; } void LoanOfficer::setAppName(string n) { userName = n; } string LoanOfficer::getFilename() { return fileName; } string LoanOfficer::getIntro() { stringstream ss; ss&lt;&lt;"Hi Welcome to " &lt;&lt;lenderName &lt;&lt;"\n Please enter your information below to see if you're approved for a loan." &lt;&lt;"\nWe have a fixed interest rate of 4.1 and term of loan is 30 years." &lt;&lt;"\nThe way we determine our loan approvals is by adding loan payment and monthly expenses," &lt;&lt;"\nand that is greater than 50% of your monthly income the loan is notapproved.\n\n"; Welcome = ss.str(); return Welcome; } void LoanOfficer::writeStatus() { stringstream ss; ss&lt;&lt;userName&lt;&lt;"_"&lt;&lt;counter&lt;&lt;".txt"; fileName = ss.str(); ofstream receiptOut; receiptOut.open(fileName.c_str()); //Writing report setting precision to 2 decimal places //returning true if able to write receipt. receiptOut&lt;&lt;" CUSTOMER LOAN INFORMATION " &lt;&lt;month+1&lt;&lt;"/"&lt;&lt;day&lt;&lt;"/"&lt;&lt;year+1900&lt;&lt;"\n\n" &lt;&lt;"********************************" &lt;&lt;"\n Your Loan Information: " &lt;&lt; "\n\n Principal: "&lt;&lt;"$" &lt;&lt; fixed &lt;&lt; setprecision (2) &lt;&lt; principal &lt;&lt; "\n\n Interest rate: "&lt;&lt; fixed &lt;&lt; setprecision (2) &lt;&lt; intRate &lt;&lt; "%" &lt;&lt; "\n\n Monthly Payment: "&lt;&lt;"$" &lt;&lt; fixed &lt;&lt; setprecision (2) &lt;&lt; mc.GetMonPymt() //here it obtains the correct monthly payment.

    1. COFormatting your code correctly makes it easier to read. Also, `string` w/o its pal `std::` in a header = no-no.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
