I Need The Answer To This C++ Assignment By Saturday Please

Please, programmers in the house. I am a 200L Maths/Computer student. We were given this assignment to be submitted on Mon. (31st). I humbly request the help of a good C++ programmer to help me and either send the code to my email address (honoura1@yahoo.com) or paste it here. Thanks and God bless. Below is the question.

1a) Write a program to test for a class named rational for performing arithmetic fraction. Use integer variables to represent the private instances variables of the class. The numerator and denominator e.g. fraction 2/4 = 1/2

b) Provide a constructor that enable an object of this class to be utilised when it is declared.

c) Provide public functions (methods) that perform each of the following;
i) add two rational numbers, the result of the addition should be stored in reduced form.
ii) print rational numbers in the form, a/b (where a is the numerator and b is the denominator).
iii) multiply two rational numbers.


I will be eagerly waiting for the answer. Thanks and God bless you all.


NACOSS,  networking the world!

Here's an example that does fractions. Start by compling this example and then modifying it to suite your needs.

Thank you very much Wallie. The program I wrote yesterday was just a little different from this. This will help me reconstruct my program. I also like the REMARK style in this one. klassnic, it's not that I wanted someone to just write a program for me and then i'll copy and submit. First of all we hav'nt even gotten to this aspect of C++ in school. It's because I have read alot ahead of the lecture that I can even understande this program. 90% of my class wont even understand the program. So Ghenghis , I do understand it. The thing is when I called for help with this problem on this problem, I had'nt really understood the questions. Once again, thank you all.
