Alright, I'm teaching myself C++, and I'm stuck on recieving information from files. Here's my code.

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
int x = 0;
string out_wanker[500];
string input_wanker;
ofstream out_file ("testfile.txt");
cout<<"Give me a file stream!"<<endl;
getline(cin, input_wanker, '\n');
out_file<<input_wanker<<" "<<"zarghly";
out_file.close();
ifstream in_file ("testfile.txt");

do
{
in_file>>out_wanker[x];
cout<<out_wanker[x]<<" ";
++x;
}while (out_wanker[x] != "zarghly");

return 0;
}


Ignore the strange variable names, I'm a strange person. but what I'm trying to do is write a string and read it back in. My hope is that "zarghly" would work as a terminator for the loop. However, thats not how it's working.

Sample input.
This is a test of how to work with file streams.

Sample output.
This is a test of how to work with file streams. zarghly (followed by roughly 500 spaces and a termination message)

So why isn't my loop terminating as it should?

Would it not be easier to use the eof() function as your termination condition, rather than having a random string?

What would happen if your random string was part of the file? You would terminate prematurely.

Have a look at this link, see if it helps:

Hope that helps.
