Re: Correct use of malloc?

what is anyone's opinion of

char *s = calloc(10, sizeof(char));

vs

char *s = calloc(10, sizeof(*s));

Re: Sane's Monthly Algorithms Challenge #2 [06-08]

Sane, my escalator solution is o(n^4) in floors and o(n^2) in escalators. It ran in way less than 10 seconds on my computer with a worst case set of data. Did you find it to take longer than that?

Re: simple questions about maps

searching for a key takes log(n) in a map. it would easily be possible to implement map as a hash table, but that will have to wait for a new standard. sgi provides a hash_map.

Re: simple questions about maps

you can check if a key exists using the find method.

if (mymap.find("test") != mymap.end())
{
// we found it
}
else
{
// we did not find it
}

Re: populate array with random nonrepeating #'s

your use of generics allows you to shuffle any type of array. my class allows for any type and any container to be shuffled. my series class is really not part of the exercise.

Re: populate array with random nonrepeating #'s

that is a lot of work to do two things. 1) create an enumerable of a series of integers 2) shuffle any enumerable of any type

your code only works for a very specialized case.
