a question on classes

i just learned that i could write classes to a file using the function fwrite(). (defined in stdio)

and i was wondering if i could write the whole class in one of its own functions, perhaps something like this:

Code:

#include <stdio.h>

class dot{
private:
	int x;
	int y;
	wchar_t* title;
public:
	void tofile(void);
///some other unnecessary functions///
};

void dot::tofile(void)
{
	FILE* file;
file=fopen("dotfile.dat","w+");
fwrite(&dot,sizeof(dot),1,file);    ///this is where i am not sure of
fclose(file);
}

Actually you can't write this class to file like this. Storing the address of the string in title doesn't help you retrieve the string value.

So do you have any suggestions?

You need to learn yourself Boost Serialization:

Also, do not put raw pointers in your class.

And of course, unless you have a very good reason, don't use C file I/O.

thanks for your reply
