What is wrong here?

Okay so I am making a small application to be used in large text files that have useless data. So all the data after the first space on each line gets deleted. i have worked all the compilation errors out except one. Here is the source.

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	string x;
	cout << "Enter file name" << endl;
	cin >> x;
	fstream file;
	file.open(x.c_str()); // open file
	if(file) 
	{
		ofstream out("data.txt");
		if(!out) 
		{ 
		cout << "Cannot open or create file."; 
		return 2; 
		} 
 
		string s="";
		char* lookfor = " ";
		while(!file.eof())
		{
			while(getline(file,s))
			{
				if (lookfor != NULL)
				{
				
					out << s.peek;
				}
			
			}
		}   
	}
		
	else
	{
		cout << "Error opening file.";
		return 1;
	}
	return 0;
}

In class string there is no variable named peek, as the compiler error says.... You could take a look at that:http://www.cplusplus.com/reference/string/string/

I think you must code it for yourself
