Search records from text file

smrizvi1

I have a Books.txt file which looks like this.

Collapse | Copy Code
Book name---------------Author
Lord of the rings---------J. R R Tolkiens
Tom sawyer--------------Mark twain
Just after sunset---------Stephen king
The shining--------------Stephen king
Oliver twist------------Charles Dickens
Huck Finn---------------Marktwain
Children on Hurin------J R R Tolkiens
Silmarilions------------J R R tolkiens

How can i make my c++ program to read this file, read records as arrays, sort them, and search either by book name or by the auhtor. If i write Tolkiends, how can i make it output all the books written by J R R tolkiens?

Code:

std::ifstream file("fileName");
std::string   line;

while(std::getline(file, line))
{
    std::stringstream   linestream(line);
    std::string         data;
    std::string                strOne;
    std::string                strTwo;

    // If you have truly tab delimited data use getline() with third parameter.
    // If your data is just white space separated data
    // then the operator >> will do (it reads a space separated word into a string).
    std::getline(linestream, data, '\t');  // read up-to the first tab (discard tab).

    // Read the integers using the operator >>
    linestream >> strOne>> strTwo;
}
 

Code:

#include <iostream>
using std::cerr;
using std::cout;
using std::endl;
#include <fstream>
using std::ifstream;
#include <cstdlib> // for exit function
// This program reads values from the file 'text.txt'
// and echoes them to the display until a negative value is read.
int main()
{
   ifstream indata; // indata is like cin
   int readNum; // variable for input value
  indata.open("text.txt"); // opens the file
   if(!indata) { // file couldn't be opened
      cerr << "Error: file could not be opened" << endl;
      exit(1);
   }
  indata >> readNum;
   while ( !indata.eof() ) { //until end-of-file
      cout << "Value is " << readNum<< endl;
      indata >> readNum; // sets EOF flag if no value found
   }
   indata.close();
   cout << "Finished Reading" << endl;
   return 0;
}
