What compiler/OS? There will probably be documentation provided with your system. There may be something like [url=http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dns/dns/dnsquery.asp]this[/url] for Windows, or [url=http://www.rt.com/man/dig.1.html]this[/url] for Linux.

[code]char state;[/code]The above is only a single character, not a string. [code]if ( state == "AL" || "Al" || "al")[/code]The above is equivalent to the following, which is not what you want.

These are my bookmarked links to various forums I regularly visit:[list][*][url]http://cboard.cprogramming.com/forumdisplay.php?s=&forumid=4[/url] [*][url]http://www.daniweb.com/techtalkforums/forumdisplay.php?s=&daysprune=&f=8[/url] [*][url]http://forums.devshed.com/f42/s[/url] [*][url]http://www.gidforums.com/f-28.html[/url] [*][url]http://www.tek-tips.com/threadminder.cfm?pid=205[/url] [*][url]http://www.cppworld.com/[/url][/list]What are yours?

It looks like you are trying to make some old Borland code for DOS. Perhaps there are some examples in the Code Snippets.

Where there is repetition, try to separate the common code. For example,[code] cout<<"Enter your selection please..."; cin>>c; cout<<"Enter the number of dice to roll..."; cin>>n; cout<<"in groups of how many? "; cin>>g; if ( c == 1 ) { D4(n,4); } else if ( c == 2 ) { D4(n,6); …

How about this?[code]while ( cin >> x >> y )[/code]What is an example of your input?

[code]#include <iostream> #include <string> using namespace std; int main(void) { string text; do { cout << "prompt: "; getline(cin, text); } while ( text[0] == '\0' ); cout << "text = " << text << endl; return 0; } /* my output prompt: prompt: prompt: prompt: hello world text = …

I believe the [url=http://www.boost.org/libs/regex/doc/index.html]boost regex[/url] is frequently recommended.

There is no function because there is no need for one. What you see is how you choose to interpret it. [code]#include <stdio.h> int main(void) { char ch = '*'; printf("ch = '%c'\n", ch); printf("ch = %d\n", ch); return 0; } /* my output ch = '*' ch = 42 …

First, why are you using the [FONT=Courier New]#include [COLOR=Red]<[/COLOR]header.h[COLOR=Red]>[/COLOR][/FONT] variation? That is generally used for system headers. User headers are generally [FONT=Courier New]#include [COLOR=Blue]"[/COLOR]header.h[COLOR=Blue]"[/COLOR][/FONT]. It makes a difference in where it looks for the files. Second, are you setting up the project correctly for multiple source files? It ought to …

Maybe try searching the [url=http://www.daniweb.com/code/c.html]Code Snippets[/url].

I'm not familiar with the libraries you are working with, but perhaps the "'non native', ie like a 'string', or 'vector'" issue is because they are not POD types?

Could you describe your problem with this in more detail?

Why don't you use the parameterized constructor? [code]int main() { int d; int b; cout << "Enter number in decimal and the Base to Convert: "; cin >> d >> b; cout << endl; [COLOR=Blue]baseType myBase(d,b);[/COLOR] myBase.decToBase(d, b); myBase.print(); return 0; }[/code]

[code] double a=123.456; char msg1[3]; sprintf(msg1,"%g",a);[/code]The string [FONT=Courier New]msg1[/FONT] only has room for 2 characters and a terminating null.

I am not familiar with [FONT=Courier New]AnsiString[/FONT], so I'd recommend reading the documentation your implementation provides.
