map and visual C++

[Somesh]

#include<map>
#include<iostre am>
#include<string >

using namespace std;

int main()
{

map <string,int> test;

test["hello"]=5;
test.insert(map <string,int>::v alue_type("bye" ,10));

typedef map<string,int> ::const_iterato r CI;

for(CI p=test.begin(); p!=test.end();+ +p)
cout<<p->first<<" "<<p->second<<endl ;
return 0;
}

The above code gives around 100 warnings on compiling in Microsoft
Visual C++ compiler.Most of which don't make any sense to me.If any
one can throw some light on the warnings.I am also posting some sample
warnings.I have tried using vector container also but that doesn't
give any error.It's only when i use map that these warnings arise.

The above code gives around 100 warnings on compiling in Microsoft
Visual C++ compiler.Most of which don't make any sense to me.If any
one can throw some light on the warnings.[...]

Please ask compiler-specific questions in a newsgroup dedicated to that
compiler (in this case, microsoft.publi c.vc.language).

Warnings can be disabled. Warnings can be ignored. But one thing is
for sure, they are not part of the language.

This has nothing to do with Standard C++, but is a Microsoft-specific
question. Go ask in a Microsoft-specific newsgroup.

Personally, I'd just disable the C4786 warning.

I got the same problem the first time I tried to use std::map too. I
have never been able to find a clean solution. It seems these warnings
are produced because VC6.0 internal class names are limited to 255
characters, but class names tend to be very long when using STL.
Solution:
either disable the warning with #pragma, it works,
either use another compiler. VC6.0 is really crappy when dealing with
templates. I recommend you to upgrade your compiler to VC7.1 which has a
far better support for templates and standard C++ in general.

USE DEV C++ : OPEN SOURCE IS THE BEST

Try microsoft.publi c.vstudio.gener al.

[OT] Or 1) compile in release mode, 2) type #pragma
warning(disable :4786) ..Visual Studio makes a file for debugging
purposes when you compile in debug mode that helps a debugger name
functions, variables, and objects correctly, and it only saves 255
characters, which is why you see some of those warnings[/OT]
