Say if

double atof(char s[ ]);
has been declared and then there is statement
sign=(s[i]=='-' ) ? -1:1;

Hi,
the code u have put is a ternary operator.
sign=(s[i]=='-' ) ? -1:1;
If user has entered a negative value the the value of sign will be -1 or else 1

Thanks

Did you try putting that into a compiler?

In the future please follow the following rules from the FAQ:

Using a good, clear thread title is important. The reasons for this are:

* We want this site to grow, many of our new members find the site using a search engine, by using a good thread title you will help us grow the site by helping us get better search engine rankings.
* Using a good title will benefit you too because other members of the forum will be less likely to skip over your thread and it allows the experts to quickly scan through the forum for questions they know the answer to.
* If the threads are well titled it allows other users to easily see if there have been any threads that could be relevant to their own current problem.
* It is in everybody's best interests to post properly titled threads as the more time the moderators have to spend on managing titles the less time they have available to give answers to the questions posed.
