    some advice please

    i have an excercise which i am having trouble with, its is regarding a vector array and searching for dupliacte entries

#include <algorithm>
#include <ios>
#include <string>
#include <vector>

int main()

      replied to real noob question
      in C
      i see i think i am getting a clearer picture now

      Code:
      std::vector<double> test(10);
      would be an array with 10 elements, indexed from 0-9

      so if one were to perform the action
      Code:
       test.size()
      it would return an integer value of the size of the array which in the above example would be 10

      we can therefore use the size() -1 to access the last index?

      please correct...

        real noob question

        hi am new at c++ and am trying my best to learn but am having a little trouble understand one aspect that has been repeated in many text books all with very vague explanations.

        i am hoping someone can clear some of this up for me.

        my question is in regards to arrays and vectors.

        i understand that c++ counts from 0+ and not the natural numbers 1+

        so an array of test(23) would be in the range...
