C++ : problem with getline()

[system]

Hi, I've written the following code just to check and it's behaving strange. It prints the string one step later... Please let me know what's wrong in it:

#include <iostream>
#include <string>
using namespace std;
int main()
{
	int t, x, n, i;
	string s;
	cin >> t;
	for(x = 1; x <= t; x++)
	{
		cin >> n;
		getline(cin, s); // eat the '\n'
		for(i = 0; i < n; i++)
		{
			getline(cin, s);
			cout << s << endl;
		}
	}
	return 0;
}

Thanks in advance and sorry if there is already a post related to this, I failed to find out
I've also tried using cin.ignore(1,'\n'); but it don't work as well.

It works as expected for me.

#include <iostream>
#include <string>
using namespace std;
int main()
{
   int t, x, n, i;
   string s;
   cin >> t;
   for(x = 1; x <= t; x++)
   {
      cin >> n;
      getline(cin, s); // eat the '\n'
	  for(i = 0; i < n; i++)
      {
         getline(cin, s);
         cout << "--" << s << "--" << endl;
      }
   }
   return 0;
}

Input:

5
asdfjhashk
ahasdkjhkasd
sdakfjlhds
dfhakssd
asdfkjhas
3
fafdsafafasdfa
sdfasdfasfasdf
adsfasfasdfdsf

Output:

--asdfjhashk--
--ahasdkjhkasd--
--sdakfjlhds--
--dfhakssd--
--asdfkjhas--
--fafdsafafasdfa--
--sdfasdfasfasdf--
--adsfasfasdfdsf--

Thanks leppy, today I also tested it in g++ and it worked fine, but it creates problem in VC6.

Yeah, getline in VC6 does have that bug. It's probably a good idea to upgrade to the latest version. (It must be inconvenient how VC6 uses __int64 instead of long long, and how you can't actually output __int64s using cout!)
