On this one I have no idea how to start.

I need to write program that will read a list of five numbers and returns them in increasing order.

First I will need to create my variables:

int a,b,c,d,e;

Then what, do I have to use the max and min to compare then I will create the output.

Thanks in advance.

What you should do is use an array. You declare an array like this:

(Toggle Plain Text)

int array[5];

What that does is make an array of variables. In this case it can hold 5 different numbers. So lets say you store the following numbers in there:

5 10 25 17 6

To get the first number in the array you would call it like this

(Toggle Plain Text)

int x=array[0];

That would set x to 5. If you had put a [4] instead of a [0] then it would have stored 6 in x.

Then you can use a couple of for loops to sort them, like this:

(Toggle Plain Text)

 
    for(j=0;j<array[j];j++)
    {
        for(k=0; k<array[k+1];k++)
        {
            if(array[k]<=array[k+1])
            {
                int x = array[k];
                array[k]=array[k+1];
                array[k+1]=x;
            }
        }
    }

(Hope I didn't give away too much)

Look up couple of the sort algorithms. If you need me to go further into detail about arrays then I can.

Nice work, could it be done without using arrays.

Can we do it with using a loop only?

Mjordan2nd · Oct 9th, 2004, 6:47 PM

It can be done, but it would be a lot more work. Arrays make it a lot more effecient.

Why not try your homwork before asking sombody to do it for you so, you understand how the answer comes about?

I am not asking you to go my homework Pizentios, I only ask to help me out to gain the idea of developing it.

Also our lecturer has no idea of what he�s teaching, that way I had to come to find the support somewhere else and I am trying my best, its not only of doing the homework its Pizentios matter of learning something too.

And as i said I didnt know how to start, so i asked for some support.

Infinite Recursion · Oct 10th, 2004, 2:27 AM

Yes. Pizentios is correct... you have posted several homework questions it seems... most of which shows that you never made a valid attempt at a solution. You will learn a great deal in the analytical, problem-solving, logical/rational thought, development and debugging processes if you do your own work. I hate for one of use to "earn" your diploma or degree for you and you get to the field and don't know what you are doing. With that said, we are all here to help... just let us know that you have put forth the effort to derive a solution first.

Mjordan2nd · Oct 10th, 2004, 3:09 AM

Well, I kind of think what he's asking. When you don't have any idea of the algorithm you're supposed to use then it's pretty hard to start off. For example, I prefer to do all my homework by myself, but on that mouse-cheese problem I didn't even know where to start, so I just posted the question to get an idea how to start, not really to get a definitive answer. The solution that I came up with took quite a bit of thinking, and was probably still a pretty crappy way to do it. Although, I do see what IR is saying, TecBrain. It is a lot more rewarding when you come up with a solution to a tough problem entirely on your own.

TecBrain · Oct 10th, 2004, 11:13 AM

I agree with you guys, you�re all right:

Infinite Recursion you said that �most of which shows that you never made a valid attempt at a solution.� That is not true, check all my posts.

Don�t forget guys that you are a programmer or at least with a good background programming skills, for me� let me see its my 2nd week of C++, so I don�t know have background knowledge.
And there is no way of me knowing how to think of how to order number in an increasing order�. That�s why I am here, I am not asking for writing the codes�..

Please don�t get me wrong�.

Infinite Recursion · Oct 10th, 2004, 11:47 AM

TecBrain, I could be wrong, just seemed like you were posting one assignment after another... I don't have time to review the posts and gather statistics.

We are all here to help.... I spent 4 years in college and yes, I've had instructors that did not know what the hell they were doing and were very confusing. So I know why you are seeking outside assistance, which is very smart. Even some textbooks can be very confusing.

Divide and Conquer, process of elimination, trial-and-error are some of the best ways to hammer out a solution. You are right, if you are new to the field there will definitely be alot of questions. I just see too much of "do my homework and email it to me" type of posts here and at other sites.

As I said, we are all here to help... as long as you all let us know what you have tried or show some other sign of making a valid effort... I have no problem helping out.
