Are you asking how you would get the length of either of those data structures? Iterate through each node in whatever structure, adding to a counter. At the end, you have the length. In an array, it is just iteration through elements, and in a list, it is iteration through the nodes.

Any easier way to get the length of an array would be to do


int arr[100];
int size = sizeof(arr)/sizeof(int);

you can do this for any data type

hell, if you're using stl c++ data types like deque, list, or any others, it is simply
list foo;
foo.size();

or stl string type use length

std::string::length() is deprecated. You are supposed to use std::string::size() like the other STL containers.
