    Fstream problem.

    How come im not getting the value for health?

    Code:
    #include <iostream>
    #include <fstream>
    #include <string>
    
    
    using namespace std;
    
    
    int main()
    {
    
    	string filebuffer = "";
    
    	int gold;
    	int health;
    
    
    	ifstream file("file.add");
    
    	file.flags(ios::hex);
    	file >> gold;
    	file >> health;
    
    	cout << (int*)gold<<endl;
    
    
    	cout <<gold<<endl;
    	cout <<health<<endl;
    	return 0;
    }
    Gold is receiving the values, but health isn't? What is the problem?
    I'm having this problem for memory adress stuff for about 2 hours now...

    What does the file say? What are you getting that you shouldn't be getting, or vice versa?

    Health is not even receiving a value.

    file.flags(ios::hex);
    file >> gold;
    file >> health;

    Gold is receiving the first line...
    Health is supposed to receive the second line.

    I think it's a problem with Hex values.

    I've always wondered about the difference between flags and setf, and now I know: flags will clear all the other flags, things like skipws which are important.

    Change the flags line to
    Code:
    file.setf(ios::hex, ios::basefield);

    Try this code:

    Code:
    #include <iostream>
    #include <fstream>
    #include <string>
    
    
    using namespace std;
    
    
    int main()
    {
    
    	string filebuffer = "";
    
    	int gold;
    	int health;
    
    
    	ifstream file("file.add");
    
    	file.setf(ios::hex | ios::basefield);
    	file >> gold;
    	file >> health;
    
    	cout << (int*)gold<<endl;
    
    
    	cout <<gold<<endl;
    	cout <<health<<endl;
    	return 0;
    }

    Make a file.add and put this in it:

    Code:
    002CFE40

    file.setf(ios::hex | ios::basefield);
    That's the ugliest comma I've ever seen.
