Im trying to read a tab delimited file into a string vector and display it. But I am not getting the desired output.

This is the file I am trying to read in and display:

1 amazon billybob@kfc.com password!23
2 facebook digitalGlut3n@ello.mail fri3dMayoNaize
3 bank.com brokeDude@sofa.com LostTheRemot3!.Crap

This is my display function:

void DisplayRecords() 

 vector<string> vRecords;
 ifstream inFile("database.txt");

 string entry;

 while (inFile >> entry) 
 vRecords.push_back(entry);
 

 for (int i = 0; i < vRecords.size(); i++) 
 if (i % 4 == 0) 
 cout << "n";
 
 cout << setw(5) << vRecords[i];
 

 cout << "nn";

And this is the output I get:

1amazonbillybob@kfc.compassword!23
2facebookdigitalGlut3n@ello.mailfri3dMayoNaize
3bank.combrokeDude@sofa.comLostTheRemot3!.CrapPress any key to continue . . .

How would I get my function to display similar to the original file with spaces between strings?

A vector of individual strings really does not make a lot of sense for structured data. A vector of structs would make more sense, eg:

#include <iostream>
#include <vector>
#include <string>
#include <sstream>

struct Record

 std::string id;
 std::string site;
 std::string user;
 std::string pass;
;

void DisplayRecords()

 std::vector<Record> vRecords;
 std::ifstream inFile("database.txt");
 std::string entry;

 while (std::getline(inFile, entry))
 
 std::istringstream iss(entry);

 Record rec;
 std::getline(iss, rec.id, 't');
 std::getline(iss, rec.site, 't');
 std::getline(iss, rec.user, 't');
 std::getline(iss, rec.pass, 't');

 vRecords.push_back(rec);
 

 for (int i = 0; i < vRecords.size(); ++i)
 
 Record &rec = vRecords[i];
 std::cout << std::setw(5) << rec.id
 << std::setw(10) << rec.site
 << std::setw(30) << rec.user
 << std::setw(30) << rec.pass
 << "n";
 

 std::cout << "n";

if your database file is fixed format.

you can get answer through below code.

void DisplayRecords() 

 vector<string> vRecords;
 ifstream inFile("database.txt");

 string entry;

 while (inFile >> entry) 
 vRecords.push_back(entry);
 vRecords.emplace_back("t");
 

 for (int i = 0; i < vRecords.size(); i++) 
 if (i % 8 == 0) 
 cout << "n";
 
 cout << setw(5) << vRecords[i];
 

 cout << "nn";

in this code, entry variable is 1, amazon, .... in while loop.

so, i added tab between each strings.

and print new line, when i%8 == 0 is true.

i wish it was helpful to you.
