#include <iostream>
#include <string>
#include <algorithm>
#include <stdlib.h>
#include <stdio.h>

#define DEBUG 0

using namespace std;


extern int  nw( 
                 string, string, 
                 string&, string&,
                 bool
              );

extern int  nw_align( 
                      int **, char **,
                      string, string, 
                      string&, string&,
                      int 
                    );

extern void  dpm_init        ( int **, char **, int, int, int );
extern void  print_al        ( string&, string& );
extern void  print_matrix    ( int ** const, string, string );
extern void  print_traceback ( char ** const, string, string );
extern int   max             ( int, int, int, char * );

does not compile, reporting the following errors:

1:unable to open include file IOSTREAM
2:----------------------------STRING
3:-----------------------------ALGORITHM
9: deceleration syntax error
13:multiple decleration for 'string'

Any idea about what's gone wrong ?

as i executed dis program in visual studio v10 im gettin some errors like;
'alignment.exe': Loaded 'C:\Users\Punith Chandra\Documents\Visual Studio 2010\Projects\alignment\Debug\alignment.exe', Symbols loaded.

This is because your visual studio settings has changed by mistake. If you are using Visual Studio 6.0. go to Tools->Options->Directories and check whether you have included all necessary include file folders

It's 2011 (almost 2012) VS6 is not (anymore) a C++ standard compiler, and has wrong support (different from no support) for many things. It should not be used as a "leraning tool".

Lot of people still work on VC6. So i really dont think VC6 is obsolete. I do not agree with your comment.

Emilio Garavaglia 16-Dec-11 5:27am

It seems to me you did not understood my "scope".

VC6 is NOT a STANDARD C++ compiler. It misses to match certain language specifications. This is a fact, not an opinion.

If you have to LEARN C++, VC6 cannot be a "reliable tool" since it teaches you something that's NOT (strictly speaking) C++.

If you have to WORK on an an existing product developed with VC6 using its non-standard features then you have to use VC6 (and that's why it is still used by lot of people).

But the two scopes an purposes are different. It's not a matter of obsolescence, but of what are you going to learn. VC6 is NOT C++. Once you know that, decide depending on what you need. But deciding assuming VC6 is a proper C++ implementation is dangerous, since may lead to a wrong decision because of a lack of information.

Since it looks you don't need MFC in you project, why don't you get a freely available modern compiler (such as Visual C++ 2010 Express) and then use the updated headers (and libraries, of course) this way:

C++

#include <iostream>
#include <string>
#include <algorithm>
#include <cstdlib>
#include <cstdio>

BTW I usually don't encourage mixing C++ streams with C-like stdio.

Solution 1

Stick a ".h" on the end of each file name:

XML

#include <iostream>
#include <string>
#include <algorithm>
#include <stdlib.h>

Becomes

XML

#include <iostream.h>
#include <string.h>
#include <algorithm.h>
#include <stdlib.h>
