Program using data file

[thecplusbeginner]

My program is not showing what i want it to.
In the data file the numbers printed were
1 1
2 2
3 3
4 4
5 5
1 5
1 4
1 3
4 5
4 2
5 1

I saved both files in the same folder and i am confused...
the numbers on top show the food and service rating. Each line counts as one customer. For example if i pick option 9, it tells me 0 people participated in the survey??

#include <iostream>
#include <fstream>					//for fstream

using namespace std;

int main(){

	ifstream infile("data.txt");	//read file into stream
	int f,s;
	int food[5];				//to store food rating
	int service[5];				//to store service rating
	int total=0,both_unsat=0,both_sat=0,both_one=0,both_5=0;
	for(int i=0;i<5;i++){		//initialize all to zero
		food[i]=0;
		service[i]=0;
	}
	while(infile >> f >> s){	//read while there are entries in the file
		food[f-1]++;			//increment food rating
		service[s-1]++;			//increment service rating
		total++;				//total number of entries
		if(f==1 && s==1){
			both_one++;			//both one
			both_unsat++;		//both unsatisfied
		}
		else if(f==5 && s==5){
			both_5++;			//both five
			both_sat++;			//both satisfied
		}
		else if(f<3 && s<3){
			both_unsat++;		//both unsatisfied
		}
		else if(f>3 && s>3){
			both_sat++;			//both satisfied
		}
	}
	int ch=0;
	while(ch!=10){			//menu for display

		cout<<"\nPlease choose a menu item."<<endl;
		cout<<"1. How many customers ranked the food as satisfactory."<<endl;
		cout<<"2. How many customers ranked the food as unsatisfactory."<<endl;
		cout<<"3. How many customers ranked the service as satisfactory."<<endl;
		cout<<"4. How many customers ranked the service as unsatisfactory."<<endl;
		cout<<"5. How many customers ranked both the food and service as satisfactory."<<endl;
		cout<<"6. How many customers ranked both the food and service as unsatisfactory."<<endl;
		cout<<"7. How many customers ranked the food and service both as 5."<<endl;
		cout<<"8. How many customers ranked the food and service both as 1."<<endl;
		cout<<"9. How many customers participated in the survey."<<endl;
		cout<<"10. Quit the program."<<endl;
		cin>>ch;
		cout<<endl;
		switch(ch){
			case 1: cout<<food[3]+food[4]<<" customers ranked the food as satisfactory."<<endl;
					break;
			case 2: cout<<food[0]+food[1]<<" customers ranked the food as unsatisfactory."<<endl;
					break;
			case 3: cout<<service[3]+service[4]<<" customers ranked the service as satisfactory."<<endl;
					break;
			case 4: cout<<service[0]+service[1]<<" customers ranked the service as unsatisfactory."<<endl;
					break;
			case 5: cout<<both_sat<<" customers ranked both the food and service as satisfactory."<<endl;
					break;
			case 6: cout<<both_unsat<<" customers ranked both the food and service as unsatisfactory."<<endl;
					break;
			case 7: cout<<both_5<<" customers ranked the food and service both as 5."<<endl;
					break;
			case 8: cout<<both_one<<" customers ranked the food and service both as 1."<<endl;
					break;
			case 9: cout<<total<<" customers participated in the survey."<<endl;
					break;
		}
	}

	return 0;
}

I'd check that the file has opened successfully. You can use is_open().

I ran the code with a text file with the data above and got 11 as the # participated.

[thecplusbeginner]

i used is open and it said there was an error...( am even more confused...if the same EXACT code works for you)

[wildblue]

Did you create your own data file on the same computer and did you double check it's called "data.txt" and in the same directory as the executable?

[thecplusbeginner]

yes. i created on notepad, named it data.txt and put it in the same visual studio folder i saved my hw in...

I tested the code on a Linux system and I don't have access to Visual Studio right now.

There's an answer to a similar problem here that might help.

If that doesn't help, I might just try having the code temporarily try to create a new file for output, and see where it puts that file.
