Hi,

 

I have a ‘char *’. I need to be able to traverse thru the string in both fwd and reverse directions.

 

Say, I have a string ‘world’. I will start with a fwd iter pointing at ‘w’ and start traversing. When I reach the letter ‘r’, I might need to start traversing in the backward direction i.e., the next char should be ‘o’ and I might again need to traverse fwd.

 

In other words, the iter should be easily convertible between the two directions. (If it could be done with relatively low cost, that’s all the more better.)

 

Thanks so much in advance,

Anant

 

Ps:

I looked at range - str_rbegin, str_rend. Also, David Abraham et al’s pdf doc on reverse iterator. I still didn’t understand how to get a nice iter that traverses both directions easily. I have a big gap in the understanding - I am not sure if I need to use a range here or boost::reverse_iterator or …

 

Thanks again.
