Need Help ASAP....

I have tried for the past week to figure this problem out and I have no idea how to do it. I need help with this ASAP. I have been working on this so long that I got headaches from it. ANY HELP WILL BE APPRECIATED!! THANK YOU.

Write a complete C++ program that demonstrates integer division and the modulus operator. Write a program objective to the screen and then ask the user to enter two integer values. Perform the division and modulus operations on these two numbers and assign the results into integers. Then repeat the operations and assign the results into float variables. Write the two values and four operation results to the screen. Use four decimal places of precision for the floating point values. Include descriptive comments.

Can we see what code you have or do you want us to write it all for you?

I'm sure you could get the answer within 5 minutes looking at an informative resource. Check out cplusplus.com's Communication through the console portion of their tutorial, or the guidebook given with the course you are taking. I'm sure you will get something going. Also read the boards homework policy: http://cboard.cprogramming.com/annou...ouncementid=39

Code:

#include <iostream.h> int main () { int a; int b; int c; int d; reurn 0; }

I seriously have no idea what im doing :(

Two numbers of type integer will result in only what is in front of the decimal place.

10/3 will result in just 3.
10%3 will result in the remainder or the numbers to the right of the decimal.

All you are doing is asking the user for two integers to divide.

You will the have to output the 10/3, manually output a ., then output the 10%3. (or whatever numbers the user inputs).

Then, with type float (or double) it is just outputting the 10/3 (which should be in type float or double).

Then just make your output all neat.

I only count 3 operations. Division with integers (/), modulo (or however it is spelled)...the remainder (%), and normal division with type float.

modulus operator %
division operator /
assignment operator (assign something) =

- write something to screen: std::cout << "words here";

- cout is part of the <iostream> file

- ask the user to enter an integer values: std::cin >> a;

- write value to screen: std::cout << a;

- using precision when outputting using cout: std::cout << setprecision(4) << a;

Trying to do this for a week? I'm sure this wasn't just handed to you your first day, so you must have been sick/not paying attention/not there when instructions were given.. try doing the opposite. Try going over what the teacher has made you write down, showed you, or handed to you.. it should provide the information. As a backup you could have followed the first couple tutorials on this site, as they would give you the knowledge to complete this assignment (besides the modulus operator part).

Thats C :eek:

*hides* read my post for the C++ version.

Yeah...ive been in class for almost a month now and its kinda hard to retain the information when i have the class 2 days a week for 3 HOURS each day and NO BREAK.

Everyone kinda zones...

Yeah i got so far....

Code:

#include <iostream.h> int main () { int A; int B; int C; int D; cout<< "\n Please enter two Numbers: "; cin>> A >> B; cout<< "\n The result of the two numbers being divided is " << A/B << "\n"; return 0; }

I would kill to have a programming course in my school, for 6 straight hours it'd be no problem to ace it and peer tutor.. too bad my school down right sucks (not enough people sign up for the classes to have them created).

*sigh*

Code:

int main() { int divisor; int dividend; int division_results; int modulus_results; division_results = (dividend / divisor); modulus_results = (dividend % divisor); double quotient; quotient = (static_cast<double>(dividend)/divisor); return 0; }

That will do everything you said (if I read it correctly).
You must do the input and output, as well as the decimal precision.

That's actually quite pathetic. If you can't focus for that long, you need to be getting more sleep. If you can't retain information, review it between classes. Don't come on the board and expect us to do your work for you. It's rude, and also against forum policies.

Im sorry that i have A.D.D.

ADD may make it tough to learn, but it's by no means an excuse to have others do your work for you. Plagiarism is a serious offence at every institution of education that I've heard of.

im not copying...Im trying to get some help. As you can see I did some of the code already...i just need some help.

You declared variables. You obviously wrote this code in a rush since you spelt 'return' wrong. And you admittedly "had no idea what you were doing". The code you wrote had very little to do with what you've obviously been learning if you were given that assignment.

And just FYI, you're using the old standard of C++. In the newer standard, standard header files do not have the '.h' extension, and header files that are also in the C standard library need to be preceded with a 'c' (though you may not be using these very much). You also need to use namespaces - the simplest way to do this until you start using your own namespaces (which will be a while...) is to just add the line, "using namespace std;" after you include all your header files.

edit: Closed, as the thread is going nowhere and the question has been answered. If anybody would like to add anything or has further issues, PM myself or another mod and the thread can be reopened or your questions answered.
