Simple question C++

[deividas717]

Hello! I have one question with my C++ program.
I would like to ask why my program prints just last text file numbers and lessons?
Here's my code

void SkPamoka(const char CD[], Pamoka p[], int & sum){
	string klase, diena, pamoka;
	int nr;
	ifstream fd(CD);
	sum = 0; 
	while(!fd.eof()){
		fd >> klase >> diena;
			while(fd.peek() != '\n' && !fd.eof() ){
				 fd >> nr >> pamoka;
	p[sum].DetiKlase(klase);
	p[sum].DetiDiena(diena);
	p[sum].DetiNr(nr);
	p[sum].DetiPamoka(pamoka);
			}
	 sum++;
	}
fd.close();
}
void Spausdinti(const char FR[], Pamoka p[], Mokytojai m[], int sum, int k, string A, int B){
	ofstream fr(FR);
	fr.setf(ios::fixed); 
	fr.setf(ios::left);
	fr << "-----------Students Timetable----------" << endl;
	fr << "| Class       |   Day       | Nr |    Lesson  |"  << endl;
	for(int i=0; i<sum; i++){
		fr << "| "<< setw(12) << p[i].ImtiKlase() << "|" << setw(10) << p[i].ImtiDiena() << "|"<< setw(9) << p[i].ImtiNr() << "|" << p[i].ImtiPamoka() << endl;
	}
}

p[i]Imtipamoka() and p[i]imtiNr() they just print me last number and last lesson on txt file why? :/

outer loop
{
  inner loop
    {
      use index
    }

  increase index
}

The inner loop writes everything to same index.

so how I need to fix it?

You do have two options:

1. Different data structure. One that has multiple number-topic entries listed for each class-day entry, just like in the file.

2. A smarter loop. Now you print class-day-number-topic-endl and that is not what you want. You want to print only the number-topic, except when the class-day differs from previous. Then you want the endl-class-day too.

while(!fd.eof()){
		fd >> klase >> diena;
			while(fd.peek() != '\n' && !fd.eof() ){
				 fd >> nr >> pamoka;
	p[sum].DetiKlase(klase);
	p[sum].DetiDiena(diena);
	p[sum].DetiNr(nr);
	p[sum].DetiPamoka(pamoka);
			}

notice the bold font

Yes without them my program just *break. But how I need to sort everythin?

[chipp]

what i mean is, you're wasting your time to re-check whether the input stream is on the end of file or not

btw

Yes without them my program just brake

*break :)

[chipp]
