Works in Dev C but not in VC++

[znerich]

Basically Im just beginnig on learning on how to program. I have this piece of code that works on Dev C but does not work on Visual C++ 2010. I would like to know what causes the error. Due to the max length limit of this post, the full error log can't be shown. Thanks to anybody who will be able to help in advance!

here is the code:



#include<iostream>
#include<fstream>

using namespace std;


int main()
{
ifstream file;
file.open("Scores.txt");
string name;
bool notFound=1;
string searchName;
int score;

cin >> searchName;

do
{
file >> name >> score;
if (name==searchName)
notFound=0;
}while(!file.eof());


if (notFound)
cout << "The name could not be found! " << endl;
else
cout << name << " " << score << endl;

file.close();

return 0;


}



the error is:

You forgot #include <string> .

Thanks. How dumb of me.
