I would put the variables in their own parenthesis's. (x1-x2) . This looks like it might be some asymptotic equation. So the question is if the difference will EVER be less than that value. Otherwise you might be waiting a very long time for the loop to terminate.

Did you look to see if it exists and what path it has?

...and the address where we should send the completed assignment! I live only to enhance your available"party time".

It's telling you that it can't find the the first file. You probably need to enter the path in the IDE Second, it saved details of the build attempt in the path specified.

Are you using an IDE? Did you try running debug?

your compiler should tell what lines they were on. the first two are simple syntax errors Perhaps the 'int' keyword problem is related to the undeclared variable 'numCols' where you ment to write: int numCols; but wrote int int which would give those exact three. Do a string search on …

Your question is too vague. For instance, is the sequence always going to linear as in your input sequence 01234567 or does the user have the ability to REALLY mix things up with an input like 90133854 ? If not, then all you would need is the low starting number …

CTRL C seems to work in many cases if it's a command line situation.

Isn't stuff like that done by setting one variable to zero in order to find the relationship between the the other two, then resubstitute that relationship? You could also do a simultaneous equations matrix. Hope this helps, It's been a while... Hope that helps

try the FULL path name.

Those are not C++ libraries. nix all of them. Just use <iostream> (no .h) You will also need : using namespace std; //directive

I guess the best way to start is to have a clear concept of what you are trying to do. I'm not sure from reading the above, but I think the ultimate goal is to make a "person" array that enters and displays personal data in different formats???? If so, …

line 124 looks a bit strange. CatesianPoint is a class, but you are using it like a typedef?

I'll second what Ravenous Wolf had to say: All you need to do is display the results! (oops)

Here's a tip GOOGLE is your friend. Whenever you have a "lookup" type question, try Google-ing it first . Enter it like this: C++ continue C++ break You may use this method for any lookup question you may have in the future. It doesn't even have to be limited to …

use a loop to keep gathering data [code] int sum =0; int tank =0; while (cin.get() !="") cin >> tank; int sum =sum+tank; [/code] I'm not sure about the "" though...

Since adding an interest rate to SOMETHING is a similar task for both checking and savings, it could be presented as an overloaded function. Especially if there were conditions placed on the interest vs. balance in the account, would make sense to do it that way. The simplest invocation might …

Seems to me that you have a bunch of rouge braces. see commented line below. There is an extra brace between each function! I'm surprised that it compiles this way.

The only thing would suggest is to lose the namespace directive and just list what you use using std::cin

I am learning C++ myself. looking at this initially, you are using "struct" which has been depreciated in C++ syntax. Secondly, your sort method (I could be wrong about this!) seems that it could give erronous output since ( I believe) it works on comparing ascii value of the names. …

Yeah, I think it's called tabbed browsing! If you don't like that, then I guess you'll have to stimulate your creative juices a bit. Anything is possible...IF YOU TRY.

in the comparison program, the first two prototypes are incorrect. You have the test condition (a,b) which makes no sense. Later on you use it correctly with (a==b). If you took the time to read the compiler errors, you could have noticed this immediately ! I learn allot from compiler …
