I normally use C#, but have started using C++ for some other sites.
How do I handle the input for:
spoj.pl/problems/PARKINGL/2
I can't figure out how to know when to make my program terminate.

At the risk of stating the obvious... Each dataset ends with a blank line, and the number of datasets is the first line of input, so simply terminate after the processing the final dataset.
simes,
No worries 
How do I read the blank line? Using scanf and cin the app just sits waiting, it's not reading the blank line.
int getInt()
{
char s[10];
cin >> s;
printf("-%d-\n",s[0]);
return atoi(s);
}I put the above sample together, it won't print anything for the blank line though. The other method was replacing the cin line with scanf("%s", &s);
Ah I see.
I've not used C or C++ for a long while now, but if you read the 1st character of the line using a %c, you'll either get a carriage return (windows) or a line feed (*nix). If you get something else, read the remainder of the line, put it all together and convert it to an integer.
But there's probably a better way!
