Answer 1

There are 2 main problems.

1. In the second for loop where you reverse the word. You do ++it rather than ++r_it, which cause infinite loop.

2. You didn't empty store1 after reversing the word. It causes the second loop reverse the first and the second word and so on.

Also a small problem, you add space when it == input.end() && space != 1. This will make the string add an additional space when the whole string contains only ONE word. Use space > 1 instead.
