Question

How do I open a binary file (for random access file processing) for reading. (ifstream) The file name is “binfile.dat”.

(c++)

Answer 1

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

int main()
{
   string line;
   ifstream ifile("binfile.dat");                               // input file
   if(ifile.is_open())
   {
       while(getline (ifile, line))               // reading first line from input file
       {
           cout << line << endl;  
       }
       ifile.close();  
   }
   else
       cout<<"Unable to open file"<<endl;
   return 0;
}
