The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Mod Operator needs to be added? Help fixing C++ program using doubles

This question was asked previously but, to no avail.
I am using code blocks as my compiler.

I have a program that I am trying to figure out.
The instructions given is:
Write a C++ program will take in the price of an item purchased and the amount of cash tendered. The program will output the amount of change and then break this down
into dollars, quarters, dimes, nickels and pennies.Use the modulus operator. You may be off by one penny, but see if
you can find a way to fix that by writing code to perform rounding. When you assign a double to an int, the decimal
portion is truncated.

Example run:

Enter the price of the item: 3.35

Enter the amount of cash tendered: 5.00

Your change is $1.65

1 dollar
2 quarters
1 dimes
1 nickel
0 pennies

Please help me figure out how to implement the mod operator and get the correct change.

I asked this question previously and the expert didn't give answer using double.
