C++ how to read string from file

[sreeharitk]

Hi all
Happy greetings to all of UBUNTU !!!!!!!!!!!! :):):):)
Hope everybody celebrating life in Planet Earth :):):)
Thanks for the great help provided so far :)
The following program is written for reading text string from a file but it is only reading first word. how to over come that?

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

int read()
{

ifstream in ("char.txt");
char str[67];
in>>str;
cout<<str<<endl;
return 0;
}

The output should be " This is a string"
However it returns only " This"
how to overcome this??!!

Stream string extraction (<<) is "formatted input" and reads items for the stream (numerical or boolean values, words).

If you want to read the plain stream contents, use get() or getline().

Thank you sir!!!!!!!!!
It worked!
I changed my code in the following way..
Thanks a lot again :)

#include <iostream>
#include <fstream>
using namespace std;
int main()
{
int i,j,k;
ifstream inobj ("char.txt");
char str [30];
inobj.get(str, 30);
cout<<str<<endl;
return 0;
}
With regards

Warning! This code is very dangerous. Please read up on null-termination of strings. Your code above may sometimes work and sometimes not work, and you do not catch error cases. You could improve it as follows:




#include <iostream>
#include <fstream>
using namespace std;
int main()
{
int i,j,k;
ifstream inobj ("char.txt");
char str [31];
i = inobj.get(str, 30);
if (i>=0) {
str[i] = '\0';
cout<<str<<endl;
}
return 0;
}
