Visual studio Error C2784

I have a problem with simple code that working with g++ compiler on Linux but I got many Errors with Visual studio professional 2012 on Windows.

The code:

string tmp = *path;
  if(tmp.length() == 0) 
    *path = Name_;
  else
    *path = Name_ + '.' + tmp;

The Error:

Error   1   error C2784: 'std::_String_iterator<_Mystr> std::operator +(_String_iterator<_Mystr>::difference_type,std::_String_iterator<_Mystr>)' : could not deduce template argument for 'std::_String_iterator<_Mystr>' from 'char'

The program points me to + operator. Also my includes are:

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

In addition I have a problems with cout <<. The operator << does not recognized by Visual studio although iostream included.

Thanks

You need to #include <string> instead of string.h (the latter declares C string functions like strstr, strcmp, etc.)

If your operand is a std::string, including <string> will probably also fix the problem with << not being recognized.

Edit: as an aside, if (tmp.empty()) is generally preferred over if(tmp.length() == 0).
