filestreams and strings

[[I.R.A]_FBi]

If i havea file name ina string(which is in a vector) how can i get the file to be opened by the stream without throwing an error?

What kind of vector are you using? And if you're using a C++ string (include <string>), you can try including <string.h> too and pass a C string to the vector using the .c_str() converter. That should work. Try something like this:

...
vector<string> v;
v.push_back( file_name );
ifstream file_handle( v[ 0 ].c_str() )
...

The 0 would of course be the index of the string you want.

ifstream html_file;
    
    for ( int i=0; i < filelist.size(); i++)
    {
         html_file.open (filelist[i], ifstream::out);//getting compile error here
         if(html_file.is_open())
         {
              //proceed
         }
         
         else
         {
             cout<<"File "<<filelist[i]<<" does not exist\n";
         }
    }

ifstream html_file;
    
    for ( int i=0; i < filelist.size(); i++)
    {
         html_file.open (filelist[i], ifstream::out);//getting compile error here
         if(html_file.is_open())
         {
              //proceed
         }
         
         else
         {
             cout<<"File "<<filelist[i]<<" does not exist\n";
         }
    }

Zap the second argument completely.

the vector neeeds a c_str() .. thanks
