Map Problem

[TISARKER]

When I compiled the following code
Then 77 warnings shows.
How can I remove those warnings.

Here is the code

Code: Select all

#include<stdio.h>
#include<ctype.h>
#include<string>
#include<algorithm>
#include<vector>
#include<map>

using namespace std;

map<string,int> M;

void main()
{

}

[Cho]

Try this code:

Code: Select all

#include<cstdio>
#include<cctype>
#include<string>
#include<algorithm>
#include<vector>
#include<map>

using namespace std;

map<string,int> M;

int main()
{
   return 0;
}

By the way, you should post in the C++ forum.

Ok Cho, I will not try to mistake this type of error.

By the way, I use Visual c++6.0.After compiling ur code two error massage shows.
1.Cannot open include file: 'cstdio.h'
2.Cannot open include file: 'cctype.h'

Does Visual c++ support above two files.?

What can I do now?.
Please help me.

V C++ does support <cstdio>,

but you should not include the .h after the header name.

Yet 77 warnings shows.
What can I do now.?

What Cho means is that #include <cstdio> but not #include <cstdio.h>

You don't have to put .h for C++ headers

Ok I have understood my mistake.
Sorry for my mistake .

But yet 77 warnings shows after compilling Cho's given code.
What is the reason.?

IIRC you have to include /EHsc option to make Microsoft's compiler happy.
i.e. use "cl /EHsc filename.cpp" for compilation.

Hi mf, Please clarify it with example.

Well, "cl /EHsc filename.cpp" was an example!
That's what you should type, if you use Miscrosoft Visual C++'s command line compiler.

If you use IDE: choose Project->Settings->C/C++ tab, replace everything in "Project Options" with "/EHsc /c".

Hi misof,

Can u briefly clarify and explain me, What was written in 77 warnings?.
I want to tell what do 77 warnings mean?.

Sorry for my poor English.

if you want to code for OJ, you should stick to gcc/g++

[Riyad]

if you are using visual C++ just add the following line in the begining of the code :

# pragma warning ( disable : 4786 )

this line will cause the STL warnings to vanish but the errors will be notified ......
