I need to find the sum and the product of the digits of the number entered. I have the sum part down but the only problem with it is that when I enter a number for the first time it gives me the right answer but when I enter another number, it just adds the sum of the first number and the sum of the second number together and then checks if the sum of the two sums is odd sorry if its kind of confusing. For the product part of the code I just can't seem to figure out how to do it.

Finally if the sum and the product both are odd I need it to say that the number entered is an Extremely odd number. This Java application checks whole numbers in the interval [, ] to see if they are "extremely odd" and "super extremely odd" numbers. Loop prompting the user to enter positive whole numbers.

Looping ends when a -1 is entered. For each number entered, check to see if its extremely odd or super extremely odd. If somebody could just explain what the requirements for the super extremely odd numbers part are saying that would be appreciated because English is not my first language.

I don't need anyone to do the whole assignment. I just need help on the parts that I'm stuck in. Thank you in advance! Learn more. How to find the product and sum of digits of a number in java? Ask Question. Asked 3 years, 2 months ago. Active 2 years, 2 months ago. Viewed 1k times.

Here is the assignment: This Java application checks whole numbers in the interval [, ] to see if they are "extremely odd" and "super extremely odd" numbers. A whole number is "extremely odd" if You manipulate the value of the entered value in your sum loop, so why do you expect you can do that again? And why don't you just create the product inside the "sum loop"? If I don't have that line in there it wont run properly, how would I change it? What would you do with "something" you need to change, but like to keep it's original state for later?

Would you create a copy? Can you do the different "thing" from the second loop in the first loop? So combining both loop bodies? Tom So I figured out how to find the product but I still cant figure out how to keep its original value. I know I'm probably missing something really obvious but I just can't understand it.

Keeping the original value is just another way to fix your problem. Active Oldest Votes.

The only difference here is instead of counting the total number of digits we are multiplying each digit by another one until the user given number becomes 0 or less than 0.

First of all, we are declaring one variable product with value 1, we are going to use this variable to store the product of all digits, now after taking input from the user, inside the while loop, we have to extract each digit by performing modulo operation.

The modulo operation returns the remainder after dividing a number by another number. If we perform modulo operation with 10 on any number it will return the last most digit, we have to multiply and store the result into the variable product. After that remove the last most digit from the number and perform the same again until the number becomes 0 or less than 0. Once the loop is completed simple print the variable product containing the product of all digit.

### How to Find the Product and Sum of Two (Or More) Numbers

First of all, let's observe that all of the digits of such a number cannot be the same. It is also clear that all of the digits should be non-zero. Now suppose that we have such a number. I don't think there are any other combinations, I looked at all small numbers Sign up to join this community.

Because it will handle arrays gracefully and without complaint, you can use it to process ranges of cells in clever, elegant ways see links to formula examples on this page. Note: Don't be confused by the double-negative.

Screw jack advantages and disadvantagesSee more below Each array has 5 items. Each item in the first array will be multiplied by the corresponding item in the second array.

We need the items in array1 to be numeric — they need to be "coerced" into ones and zeros. This is where the double-negative comes in. The last column "Product" represents the result of multiplying the two arrays together. This example expands on the ideas above with more detail. These are not normally array functions, but when they are given a range, they create a "result array". This can be a good way to save space in a worksheet, by eliminating the need for a "helper" column.

For example, assume you have 10 different text values in A1:A10 and you want to count the total characters for all 10 values. You could add a helper column in column B that uses this formula: LEN A1 to calculate the characters in each cell. Then you could use SUM to add up all 10 numbers.

Criteria can be applied to dates, numbers, and text. Formulas are the key to getting things done in Excel. You'll also learn how to troubleshoot, trace errors, and fix problems.

**Program to find sum of digits of a number**

Instant access. Skip to main content. Return value.Any integer shown to be a sum-product number in a given base must, by definition, also be a Harshad number in that base. Sum-product numbers can be extended to the negative integers by use of a signed-digit representation to represent each integer.

The example below implements the sum-product function described in the definition above to search for sum-product numbers and cycles in Python. From Wikipedia, the free encyclopedia.

The Product table contains data on the maker, model number, and type of product 'PC', 'Laptop', or 'Printer'. It is assumed that model numbers in the Product table are unique for all makers and product types. Each personal computer in the PC table is unambiguously identified by a unique code, and is additionally characterized by its model foreign key referring to the Product tableprocessor speed in MHz — speed field, RAM capacity in Mb - ram, hard disk drive capacity in Gb — hd, CD-ROM speed e.

Result set: model, sum of digits Please tell me how to solve it. I am of intermediate sql skill and cant solve this. Juan Carlos Oropeza We fix code you've written. We're not here to write it for you. This is really a math problem more than a "SQL" problem. If your ID is a string you'll have to convert to int. If it's longer than 9 characters you should use a "bigint" or break it into pieces.

MarcB SO does much more than "fix code you've written. We answer questions by providing information and sharing knowledge. Some narrowly scoped questions asking for code are fine. But however you describe it, please don't foster the notion that we're here to fix other people's code; that's no better than just writing code for people. We're also NOT a code writing service.
