Outputting contents of text file to screen.

[Michael_Bray]

Hi,

Just a quick C++ problem. Trying to open a text file and output the contents to the screen. Seemingly an easy task, but I can't find a good example on the net anywhere

My code is:

#include <iostream>
#include <fstream>
#include <string>

int main()
{

 ifstream ins;
 string word;
 char c;
 
 // Open up the text file and read the data.
 // Print and error if we can't open it.
 ins.open("data.txt");
 
 if(ins.fail())
 {
  cout << "Cannot read file." << endl;
  return 0;
 }
 
 while (ins >> word)
 {
  ins.get(c);
  cout << c;
 } 

}

It compiles and executes, however it doesn't print anything to the screen. I know I have done something really stupid, however I don't have a clue what it is.

while (ins >> word)
 {
  ins.get(c);
  cout << c;
 }

What you're doing here is retrieving a word from the file, then getting another character and printing that. Try cout << ' ' << word to print the word out.

I would suggest using getline though, otherwise you risk losing information from the file:

while(!ins.eof()) {
    string line;
    getline(ins, line);
    cout << line << endl;
}
