[QUOTE=logicmonster;1143033]How did you solve this? I'm having basically the same problem.[/QUOTE] What makes you think after two years this guy is just waiting around for you to ask this? If it's the same problem, try reading the thread and get the same help he got.

Opening a file requires a C-style character array, not a C++ string. [B]Jonsca[/B] has posted your answer. I just thought I add why.

I suggest displaying all the values before and after you try the insert. Display the array, used, current_index, and any other variables that will help you figure out the problem. Run the code in the debugger is also a good idea.

You're welcome in retrospect. Why did you post this? What kind of response are you expecting? you didn't even ask a question.

You need to ask a question about what you don't understand. Not just post your assignment: 1) it looks like you want us to do it for you 2) we have no idea what you're having trouble with When posting, details are more important than posting the assignment.

While you're googling, google for [I]satire[/I].

I don't see a problem. Maybe you should post the entire error, not paraphrase it. Wonder if it has to do with using [B]math.h[/B] instead of the C++ [B]cmath[/B]. I doubt it, but [B]cmath[/B] is the correct header.

Good job. nicely formatted code, but you used [iCODE]conio.h[/iCODE]. What grade did you get?

Because you are expecting the language to do the work for you. When you read strings, [I]you[/I] need to deal with the strings yourself. And since we have no idea what you are reading and trying to do, it's hard to point you in a direction. You need to understand …

So what seems to be wrong? We aren't psychic...

With your lack of [url=http://www.gidnetwork.com/b-38.html]formatting[/url] I must be missing the [ICODE]for[/ICODE], [ICODE]do-while[/ICODE], or [ICODE]while[/ICODE] statements that start your loop

[QUOTE=its_yogy;1141621]// Also i wud be happy to ...[/QUOTE] And we [B][I]would[/I][/B] be happy if you'd use CODE tags and [url=http://www.gidnetwork.com/b-38.html]format your code[/url]

We don't know where either, but there certainly is one missing. It all depends on what is part of your function and what isn't.

In the same scope, yes. In different scopes, no. But it could be very confusing to anyone reading the code. Generally not in functions as you have them, though. Be careful if defining variables within code blocks ([ICODE]if[/ICODE], [ICODE]for[/ICODE], [ICODE]while[/ICODE], ect)

Look up the [ICODE]unload[/ICODE] or [ICODE]terminate[/ICODE] event handlers for your form.

Read the file line by line and when you get to the line you want, stop. Might need an [iCODE]if[/iCODE] statement

Didn't that work?

Look up a [B]bubble sort[/B]. That is the easiest sort to implement.

Look up the function [iCODE]isalpha()[/iCODE] and test each character after you read the line. Also, [url=http://www.gidnetwork.com/b-56.html]see this[/url] about gets(). And [url=http://www.gidnetwork.com/b-38.html]see this[/url] about formatting. Yours is not very good.

You start by choosing a language Look you the for loop Add code to support the loop

You open the files in [ICODE]main()[/ICODE], you don't check if they opened properly until you've called your function. Bad form. Open and check immediately. That way you don't waste time and confuse your brain cells later. Then you use [ICODE]scanf("%s"...)[/ICODE] which is dangerous.

You have to deal with the array index and the loop index [B]i[/B] separately. Only increment the array index if -1 is not read. If you see the -1, do not increment the array index.

A mid-90's [I]Alicia Silverstone[/I] movie pops into mind for some reason.

First thing I see is using C-style headers and C input. Get rid of all the C headers ([ICODE]conio.h, stdio.h[/ICODE]) and stick with [ICODE]iostream[/ICODE].

Post the freakin' errors. We can't help you if you keep the errors a secret.

When you loop through the line you convert only the digits. But if one of the locations is not a digit, not only do you skip it in the source string, but you also skip the same position in the destination array -- leaving uninitialized data in that position.

Why are you resurrecting a 6 year old thread as if you have something to add?
