Thread: Table Problem2-(a different code)

Sorry to bother you all with a similar one as my previous.
I wrote below program for the purpose of, first reading 2 files. Think of these 2 files as the 2 columns of a data table. That means, 1st column is on the 1st file and the 2nd column is on the other file. On execution, the program must combine these 2 data columns(2 files) into a neat table( with solid 2 columns, of course), and write back it into a 3rd file.
My problem is that, the 2nd column doesn’t get printed in a straight column on the 3rd file. They get wiggled (If you can please test the program). I tried to solve this problem by inserting white spaces into the strings to align all of them along a single vertical line, but it didn’t worked because I regarded the lengths of all characters as the same, which is not the reality. I can’t see any way to do this aligning right, so can you please help?

Code:

#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;

void adjoin();
void rprtprint();

void main()
          {
          adjoin();
          rprtprint();
          }

void adjoin()
          {
          char* f1name = "LFILE.dat";
          char* f2name = "RFILE.dat";
          char* f3name = "LRFILE.dat";
           
         ifstream tfile1(f1name, std::ios::in);
         ifstream tfile2(f2name, std::ios::out);
         ofstream ofile(f3name);
          
          string f1str, f2str;
          vector <string> TRL;

          int fullLen = 45, freeLen=0, cnt=0;
          // read & store
          while(!tfile1.eof()){
	cnt++;
	getline(tfile1, f1str);
	getline(tfile2, f2str);
	freeLen = fullLen - f2str.length();
	TRL.push_back(f1str);
	// attempt to put even spaces. but isn't working exactly because of the various lengths of
	// characters
	while(freeLen>0){
	TRL.push_back(" ");
	freeLen--;
	          }
	TRL.push_back(f2str);
	TRL.push_back(".");
	}

          // write
          int i = 0;
          while(i < TRL.size()){
	ofile<< TRL[i];
	i++;
	}
          }

void rprtprint()
          {
          char* ifname = "LRFILE.dat";
          char* ofname = "PRINTFILE.dat";
           ifstream ifile(ifname, std::ios::in );
           ofstream ofile(ofname, std::ios::out );
           string fstr;
          while(!ifile.eof()){
	getline(ifile, fstr,  '.');
	ofile<< fstr;
	ofile<< "\n";
	}
          }
