C + + Read TXT file

1. Progressive read-In

void readtxt (string  file) {    ifstream infile;     Infile.open (File.data ());    //     assert (Infile.is_open ());   //     string  s;      while  (Getline (infile,s))    {        cout<<s<<endl;    }    Infile.close ();              // }

2. Read-by-character (ignore spaces and carriage returns)

void readtxt (string  file)

  Infile.open (File.data ());  //  connect the file stream object to the file  assert (   Infile.is_open ()); //     char      C;  while  (!infile      >>     C;   

 cout<<c<<endl; } Infile.close ();  // }

3. Read in characters (including spaces and carriage returns)

 void  readtxt (string   file) {Ifstream infile;   Infile.open (File.data ());  //  connect the file stream object to the file  assert (   Infile.is_open ()); //     char      C; infile   >>     NOSKIPWS;  

  while (!  Infile.eof ()) { infile>>C; cout<<c<<endl; } Infile.close ();  // }
