Write a top-down design and a C++ program with functions to help you balance your checking account. The program should let you enter the initial balance for the month, followed by a series of transactions. For each transaction entered, the program should echo-print the transaction data, the current balance for the account, and the total service charges. Service charges are $0.10 for a deposit and $0.15 for a check. If the balance drops below $500.00 at any point during the month, a service charge of $5.00 is assessed for the month. If the balance drops below $50.00, the program should print a warning message. If the balance becomes negative, an additional service charge of $10.00 should be assessed for each check until the balance becomes positive again.</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table><table border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="5"></td> <td colspan="3" height="12"></td> <td rowspan="5"></td></tr><tr><td colspan="3"></td></tr><tr><td></td> <td><font face="Times New Roman, Times, Serif" size="3">A transaction takes the form of a letter, followed by a blank and a </font><font face="Courier New, Courier, Mono New, Courier, Mono" size="3">float</font><font face="Times New Roman, Times, Serif" size="3"> number.

In this problem you are to design and implement a Roman numeral calculator. The subtractive Roman numeral notation commonly in use today (such as IV, meaning "4") was used only rarely during the time of the Roman Republic and Empire. For ease of calculation, the Romans most frequently used a purely additive notation in which a number was simply the sum of its digits (4 equals IIII, in this notation). Each number starts with the digit of highest value and ends with the digit of smallest value. This is the notation we use in this problem.</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table></td></tr></table><p><font size="0"></font></p>聽 </td> </tr> <tr> <td align="left" width="30%" style="background: #EEF3E2"><a style="color: blue; font-size: 120%; font-weight: bold; text-decoration: none; font-family: verdana;" href="page_384.html">< previous page</a></td> <td align="center" width="40%" style="background: #EEF3E2"><strong style="color: #2F4F4F; font-size: 120%;">page_385</strong></td> <td align="right" width="30%" style="background: #EEF3E2"><a style="color: blue; font-size: 120%; font-weight: bold; text-decoration: none; font-family: verdana;" href="page_386.html">next page ></a></td> </tr> </table> </body> </html>⌨️ 快捷键说明
