Problem 3: 30 As programmer, the local retail store asked you to develop a function named formatDollar that inserts commas and a $ sign at appropriate locations in a string object containing an unformatted dollar amount. As an argument, the function should accept a reference to a string object. You may assume the string object contains a value such as 1084567.89. The function should modify the string object so it contains a formatted dollar such as $1,084,567.89. Similarly 425389.35 will be formatted as $425,389.35. For this problem, use the supplied currency.cpp file and modify/insert your code to complete the task and generate the following output Enter a dollar amount in the form nnnnn.nn : 45879357.322 Here is the amount formatted: $45,879,357.322 Hint: Use string class find () method to find the occurrence of the decimal point
