Hi I'm working on a spoj problem that requires reading in a series of inputs in cin until a blank line, for example, 1 2 3 4 5 6 10 20 30 *blank line here* I'm noobishly new to c++ so I'm using cin>> to read in each number, but i don't know when to stop reading in. Is there a "blank line character"? When i program in java i would read in a string, check if it's null, if not then parse it - not sure if that's the way to go in c++. So, can someone give me suggestions? |

Hi, Remove whitespace and newline, and if you have an empty string, you have a blank line. Or count them and compare to length; same effect, faster. Or is you are using String, look through the STL or stdlib for a trim type operation or smart empty test. Cheers |
