reading from file

[Behzadsh]

hi,

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

save function

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

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

load function

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;
	}
}
