Write files from TXT into 2D array

[kemnet]

Hello ALl im new just wanted to ask a quick question thanks.

so im writing a program that reads in data from a ".txt" file and im supposed to use it to do computations


so I figured i should write the values into an array(or 2D array)
so i wrote the code below:


So this works except that my file "example.txt." looks like this

5.5 2.1
2.7 4.3

but when i write it into my array and executes it appears as

5.52.12.74.3

one big value

is there a better way to write it into my array so ill be able to reference one value at a time? or a different way i should go about with this problem?
thanks.
Ive read a few issues similar to mine on forums and got helped up too this far just not as far as my problem

#include "stdafx.h"
#include<iostream>
#include <fstream>
#include <iomanip>
#include <string>
#include <conio.h>
#define newline '\n'
using namespace std;


float result = 0;
int main()
{
// Read Data File into a 2-D Array
ifstream inFile ("example.txt");
inFile.precision(2);
inFile.setf(ios::fixed, ios::showpoint);
  
 
  // Declare Variables to Store Array Information
  int parcel [3] [3];
float dis [3];
  int id [3];
  int A=0;
  int B=0;
  int c=0;


//  Text File
  	ifstream inStream;
  	inStream.open("example.txt");
 
  	if (inStream.fail()) {
  	cout<< "Can't open file!\n";
  	system("pause");
  	}
 
  	else {
  		while (!inStream.eof()) {
 
 // write into Array
  		for (int i = 0; i <2; i++) {
  		inStream >> dis[i];
		result =dis[i];

		cout << result;"\n";
		
	}
		
  	}
  	// Close File

  	inStream.close();
	system("pause");
		}
  }

You need to write the seperating spaces newline characters too.

Thanks for the tip but i changed it and the output and problem remains the same...i need to find a way to separate the output.

i changed it and the output and problem remains the same

Changed it how?

[kemnet]

cout << result;
\n"; 

but the whole text file is still written too one line. dont i have to increment the array, so each "space" in the array gets one?

cout << result;
\n";

sorry but that's nonsense -> cout << result << endl

[kemnet]

oh you're right I was wrong. thanks
Still
the out put was

5.5 
2.3
10.0
 24.2

im still trying to get it to be

5.5 2.3
10.0 24.2

if possible please

[coder777]

inStream >> dis[0] >> dis[1];
cout << dis[0] << " " << dis[1] << endl;

so you don't need for (int i = 0; i <2; i++) and result and stuff

does that reading really work?

[kemnet]

Thanks alot

[kemnet]

well actually how am i too reference lets say "24.2" so i can work on it separately, Also I did the computations on my value and im ready to write them back too another text file so i did

  myfile.open("fdc.txt");
myfile<< labs[0] << " " << labs[1] <<" "<<labs[2]<< " " <<kg<<endl;	

There for i did

if (labs[1]<2)
	cout<<labs[0] << " " << labs[1] <<" "<<labs[2]<< " " <<kg<<endl;			

i get the correct results from this but its not letting me save it to a variable so i can try to write the variable to my text file

[coder777]

what are you trying to do and how does it result in an error? show some code

[kemnet]

OK for example im taking
5.5 2.3
10.0 24.2

from a text file,
-writing it into an array
-* by 2
-but when i write it back to my text file i only get the last line and its not letting me save the whole array to a variable

	inStream >> labs[0] >> labs[1]>>labs[2];
//cout << labs[0] << " " << labs[1] <<" "<<labs[2]<< endl;	


parcelkg=labs[1];

kg=parcelkg*2;
//cout<<kg<<endl;
if (labs[1]<2)
	rewrite=labs[0] << " " << labs[1] <<" "<<labs[2]<< " " <<kg<<endl;	 //rewrite=float 

[LittleQuick]

cout << result;
\n"; 

was done incorrectly. You are missing a quote it should look like:cout << result << "\n"; or cout << result << endl;

[kemnet]

yea ty :) got that
