will be helpful for those in need Assuming, filename is of type std::string, I can think of couple of ways of resolving your problem.
code :
remove((filename+".txt").c_str());
namespace myapp
{
    int remove(std::string const& filename)
    {
        return std::remove(filename.c_str());
    }
}

myapp::remove(filename+".txt");

like below fixes the issue I try to post a data to a Restful service, but I get error while doing this; The restful service methods parameters is
code :
final List<String> SelectedId = new ArrayList<String>();
SelectedId.add("8050");
SelectedId.add("7910");

final String[] strarray = SelectedId.toArray(SelectedId.size());

namevaluepairs.add(new BasicNameValuePair("groups", Arrays.toString(strarray)));

Hope this helps SQL Server doesn't do (full) expression parsing when you call a stored procedure. This is definitely an area where a small change would be highly convenient, although there are probably good reasons for the limitation.
As mentioned in a comment, use a separate variable:
code :
DECLARE @arg varchar(256) =  'LP_' + @WhID + '_COUNTER';
EXEC @v_nReturn = sp_get_next_value @arg;

hope this fix your issue char * fgets ( char * str, int num, FILE * stream );
fgets() Reads characters from stream and stores them as a C string into str until (num-1) characters have been read or either a newline or the end-of-file is reached, whichever happens first.
