Thread: reading from file

hi,

I save a string value to a file, Now I want use this value again, but null return

save function

Code:

int save_pass(void)
{
	/* function variables */
	FILE *fp ;
	int i ;
	/* function process*/
	fp = fopen("pass", "wb");
	if(!fp)
	{
		return 1;
	}
	if(&newPassword)
	{
		fwrite(&newPassword, sizeof(string), 1, fp);
	}
	return 0;
}

comparing two strings

Code:

		if (password == newPassword){
			cout << "corect";
		}
		else {
			cout << "Invalid";
		}

load function

Code:

int load_pass(void)
{
	/* function variables */
	FILE *fp ;

	/* function process*/
	fp = fopen("pass", "rb");
	if(!fp)
	{
		return 1;
	}

	fread(&newPassword, sizeof(string), 1, fp);
	if(feof (fp))
	{
		return 0;
	}
}

Now I'm using these

Code:

int save_pass(string opass)
{
	ofstream outClientFile( "pass.dat", ios::out );
	if (!outClientFile)
	{
		cerr << "File could not be created" << endl;
		return 1;
		exit (1);
	}

	outClientFile << opass;

	return 0;
}

string load_pass(void)
{
	string ipass;
	ifstream inClientFile( "pass.dat", ios::in );
	if (!inClientFile)
	{
		cerr << "File could not be Opened" << endl;
		exit (1);
	}

	inClientFile >> ipass;

	return ipass;
}

Code:

newPassword = load_pass();

but one problem, how could I write in file binnery? if I open pass.dat I will see the password
