Error in placing output to txt using <fstream>

[duckii]

Hey this is my second time posting here, I have another question to ask. I wanted to write a text file recording the patient's particular and medical fees. But I encounter 2 problems.

1) I am using 2 different classes, class Patient and class Fee and using inheritence doesnt solve the problem.

2) I try to seperate the file this way although I think it's wrong.

void Patient::Invoice0(void)
{	ofstream outFile;
	outFile.open("Patient Fee.txt");
	outFile<<"Seng Tock Tan Hospital"<<endl;
	outFile<<"Name : "<<name<<endl<<"NRIC : "<<NRIC<<endl<<"Phone Number : "<<phoneNumber<<endl;
		
	outFile.close();
}
void Fee::Invoice(void)
{
	ofstream outFile;
	outFile.open("Patient Fee.txt");
	//outFile<<"Seng Tock Tan Hospital"<<endl;
	//outFile<<"Name : "<<name<<endl<<"NRIC : "<<NRIC<<endl<<"Phone Number : "<<phoneNumber<<endl;
	outFile<<setfill('*')<<setw(90)<<"\n\t\t\tPatient' Fee schedule"<<endl;
	outFile<<setfill('*')<<setw(66)<<"*\n";
	outFile<<"\t\t\tCLASS OF WARD ACCOMONDATION\n";
	outFile<<setfill('*')<<setw(66)<<"\n";
	outFile<<"\t\t\t"<<"A\t\t"<<"B\t\t"<<"C\t\t\n";
	outFile<<"Acute Ward\t"<<"\t$230"<<"\t\t$150"<<"\t\t$75\n";
	outFile<<"Intensive care unit"<<"\t$500"<<"\t\t$300"<<"\t\t$150\n";
	outFile<<"Consultation Fee"<<"\t$50"<<"\t\t$40"<<"\t\t$25\n";
	outFile<<"Total\t\t"<<"\t$780"<<"\t\t$490"<<"\t\t$250\n";
	outFile<<setfill('*')<<setw(66)<<"\n\n";
	outFile<<"You have choosed Ward "<<choice<<endl;
	outFile<<"This ward will cost you $"<<price<<endl<<endl<<endl;
	outFile<<"You had stayed in this hospital for "<<day<<" days."<<endl;
	outFile<<setfill('*')<<setw(80)<<"\n\t\t\tOther Fees"<<endl;
	outFile<<setfill('*')<<setw(67)<<"*\n";
	outFile<<"Type 1:Back surgery\t$7800\nType 2:Ear surgery\t$4900\nType 3:Plastic surgery\t$5000\nType 4:Nose surgery\t$3500\nType 5:Leg surgery\t$6000\n";
	outFile<<setfill('*')<<setw(67)<<"\n";
	outFile<<"You have choosed surgery type "<<surgery<<endl;
	outFile<<"This will cost you another $"<<others<<endl<<endl<<endl;
	outFile<<setfill('~')<<setw(67)<<"\n";
	outFile<<"Type 1:A\t$1000\nType 2:B\t$2500\nType 3:C\t$1500\nType 4:D\t$1700\nType 5:E\t$600\n";
	outFile<<"You have choosed surgery type "<<surgery<<endl;
	outFile<<"This will cost you another $"<<others<<endl<<endl<<endl;
	outFile<<setfill('~')<<setw(67)<<"\n\n\n";
	outFile<<"The total payment is $"<<Total;

	

		
	
	outFile.close();


}

Because the second function might just overwrite the first.

Note: There's no error while building or compiling, but the output only shows the second function and totally ignoring the first.

Thanks in advance.

To open a file for appending you'll need to use the ios::ate flag. Reference documentation here:
http://www.cplusplus.com/reference/iostream/fstream/open.html

Good luck!

I am looking at it now, thanks Duoas, presentation of my project is today *nervous*

[duckii]

YES IT WORKS! ^^ thank you so much Duoas.

May i ask what's the difference between ofstream and fstream? Or are they the same?

I can't believe the school took out the ios::ate flag from the chapter, it's going to be so useful and efficient since we are dealing with classes. tsk.

THANKS AGAIN!

[Duthomhas]

Schools often lag behind standards... Alas.

An fstream is derived from both an ifstream and an ofstream, so it can do both input and output.

Good luck on your project!

[duckii]

wait! There's a problem.

void Patient::Invoice0(void)
{
	fstream outFile;
	outFile.open("Patient Fee.txt");
	outFile<<"Seng Tock Tan Hospital"<<endl;
	outFile<<"Name : "<<name<<endl<<"NRIC : "<<NRIC<<endl<<"Phone Number : "<<phoneNumber<<endl<<endl;
	outFile.close();
}
void Fee::Invoice(void)
{
	fstream outFile;
	outFile.open("Patient Fee.txt", fstream::in|fstream::app);
	outFile<<endl<<endl;
	outFile<<setfill('*')<<setw(80)<<"\n\t\t\tPatient' Fee schedule"<<endl;
	outFile<<setfill('*')<<setw(66)<<"*\n";
	outFile<<"\t\t\tCLASS OF WARD ACCOMONDATION\n";
	outFile<<setfill('*')<<setw(66)<<"\n";

	outFile<<"The total payment is $"<<Total;

	outFile.close();
}

There's a problem. My textfile will not overwrite the previous data with ios::trunc flag. It continues on and on, i want it to start on a fresh page everytime it resets. Any solutions?

[Duthomhas]

I see no trunc there. Make sure line 4 reads:

outFile.open("Patient Fee.txt",ios::out|ios::trunc);

Also, on line 12 you tell the computer that you are going to read from the file only. It should say:

outFile.open("Patient Fee.txt",ios::out|ios::app);

Hope this helps.

[duckii]

Problem solved.

Thank You very much, my group has scored 49/50 for program layout, output and interface.

Another 50 marks will go to individual, feel much more relief and free now.

Thank You for your help! I will repay you if I know your address :P
