I have been trying to write this program for this class that I'm in.

The main objective is to make it able to save drivers to a file and then just be able to look up the drivers and then save them back to the file.

I thought that if i added a string instead of a charicter array then the code would run better because i was facing a corruption error with the char array and now it is giving me trouble about bianry operators of >>

here is my code to main.cpp i know it is a bit slopy with all the functions in one class and such but I need help also clearscr(); is part of my clear.h header that i have been working on.

// Austin Gould

// drivers project
// main.cpp

#include <process.h>
#include <conio.h>
#include <iostream>
#include <fstream>
#include "clear.h"

class data{

      public:
    	  void lookup();
    	  void edit();
    	  void makedriver();
    	  void deletedriver();
		  void saveordelete();
		  bool sod;

      private:
		  std::string name;
		  int eff;
    	  //void save( void * );

};

void saveod( void * );

int main(){

    char x = ' ';

    class data d;

    while( x != 0 ){

		   clearscr();

           std::cout<< "What would you like to do" << std::endl
                    << "[L]ook up a driver's stats" << std::endl
                    << "[E]dit driver's stats" << std::endl

		   std::cin>> x;

           tolower ( x );

           clearscr();

end errors

I'm using visual studio pro 2008

You did not post clear.h as far as I can tell.

I STRONGLY encourage you to use the "this" pointer explicitly. e.g.
in data::lookup() - std::ifstream lookup( this->name ); instead of std::ifstream lookup( name ); It makes code much more readable.

Also, you'll get a bunch of errors because the ifstream constructor doesn't accept an std::string, you have to use

std::string a = "test";
std::ifstream lookup( a.c_str());

instead of

std::string a = "test";
std::ifstream lookup( a);

Hope that helps get you a bit farther.

Dave

Thanks but i don't really understand what the this pointer does and in the end should it look like this

std::ifstream lookup( this->name.c_str() );

could you explain the this pointer it would help me much more.

Also it still gives me the long list of errors and the >> binary operator no operator found at the right error.

There are plenty of tutorials on the 'this pointer'. The short version is yes,

std::ifstream lookup( this->name.c_str() );

is what it should look like. The "this->" doesn't actually change anything (in this case), it just lets the reader know that "name" is a member variable of the class the function we are in belongs to.

I suggest you make the smallest compilable bit of code that produces the errors you're seeing. That will help you isolate the problem. If you still can't figure it out, it will help us debug it much easier for you.
