linked list (c#)
- 5. Operations a programmer performs with a list data structure. Operation Name Description createList() Create a new list (presumably empty) copy() Set one list to be a copy of another clear(); Clear a list (remove all elements) insert(X, ?) Insert element X at a particular position in the list remove(?) Remove element at some position in the list get(?) Get element at a given position update(X, ?) Replace the element at a given position with X find(X) Determine if the element X is in the list length() Returns the length of the list.

Editor's Notes
- In the above code, we execute a for loop to traverse the array. The number of execution of this loop is equal to the size of the list. This for loop gets terminated when the value of loop variable ( j ) increases from the size of the list. However we terminate the loop with the break statement if the element is found at a position. When the control comes out from the loop, we check the value of j . If the value of j is less than the size of the array, it means that the loop was terminated by the break statement. We use the break statement when we find the required element (x) in the list. The execution of break statement shows that the required element was found at the position equal to the value of j . So the program sets the current position to j and comes out the function by returning 1 (i.e. true). If the value of j is greater than the size of the array, it means that the whole array has traversed and the required element is not found. So we simply return 0 (i.e. false) and come out of the function.
- You may notice here that we are returning the size {in the length () }of the list and not the size of the array being used internally to implement the list. This size is the number of the elements of the list, stored in the array.

- You don't need to use pointers to create a linked list in C#. Just store an object reference to the next list element.
