HELP with text formating

Hey all , I started to learn C++ recently and I wud need some help on something.

Here is my file.txt:

Code:

Belgique               30510     10274595         Euro

Here is my code:

Code:

int main()
{
   string filename,country,money;
   int population,sup;  
   cout << "Wuts the name of the file to read ?" << endl;
   cin >> filename;
   
   ifstream reading;
   reading.open(filename.c_str());
   if(reading.fail()) {
      cerr << "Error cudnt open the file" << filename
           << endl;
      exit(EXIT_FAILURE);   
   }
   
   while(reading >> country >> sup>> population>> money){
      cout << country<< " "<<sup<< " "<<  population << " "<<money<< " "<< endl;
   }
   
   reading.close();

Here is my question:

If I want the text after i read it to be in the same format as the original (the same alignment) how can I do? I know the command setw() but it only do for example ___country ______money ... Hope someone can answer

Edit your post and put code tags around the contents of file.txt so we can see the proper alignment (otherwise the forum software removes extra spacing).

To fix the alignment, you'll probably need to use io manipulators from <iomanip>. Perhaps setw, or a combination of setw and setfill will help.

ya i noticed my text wasnt aligned .. well this is my problem isnt it LOL ... fixed it hehe

Well I know about setw but it align to right... how do I align to left???

There is another io manipulator that will adjust that, but I don't know which it is off the top of my head.

It might be std::left.

its still not working .... any idea??? well at least I guess im not the only one to ignore the answer lol

Post your latest effort, not just an information-free "it doesn't work".

To left-align:

Code:

std::cout << std::left << std::setw(10) << object;

I'm pretty sure that left and setw can be in any order, but they have to be sequential.

lol my lastest effort ... ya ok i tried this command:

Code:

setf(ios::left)

and it gave me : error primary expression expected before.... and i included iostream,iomanip and namespace std ... so i didnt get that part ... honnestly i never had to format any text before so I have no clue how to use those... all I used was setw() but it doesnt seem to be enough to solve my problem...

Hmm, it seems I was wrong (from http://www.fredosaurus.com/notes-cpp...ipulators.html):

[std::]left: Left justifies output in field width. Only useful after setw(n).

Try this, see what happens.

Code:

std::cout << std::setw(10) << std::left << object;

Unfortunately, I don't have a compiler on this computer, but Dinkumware doesn't seem to mind this:

Code:

#include <iostream>
#include <iomanip>
#include <cmath>

int main() {
    const double pi = std::atan(1) * 4;
    std::cout << std::setw(10) << std::left << pi;
    return 0;
}
