Errors:
-endl is not used with cin--AFAIK
-for the condition for a do...while loop, you used {} instead of ()
-also, the ';' should have come after ')' for the while part.
Thank you very much!!! But it still doesn't work how it's supposed to do, if I type in "1" as the starting number and e.g. "7" as the ending number i want it to count like:
1
2
3
4
5
6
7
