Thread: Ofstream and Ifstream

Code:

#include <iostream>

#include <fstream>

using namespace std;
typedef string str;
void main()
{
  char wrd[50];



  ofstream fout("shorttext.txt");

  fout << "Hello World";
 
  fout.close();
  
  
  ifstream fin("shorttext.txt");

  fin >> wrd;

  cout << wrd;
  fin.close();
}

In the above code when run it will print the text to a file but will only read one word how would I have it read the whole line.

fin.getline(wrd,49,'\n');

The 49 is the max number of characters to get, and the \n is the char to stop at. So this line will read in 49 chars or a whole line, which ever is smaller
you have to leave room for the null terminator, which is why you have to take 1 away from the array size
