Simple example of creating a static 'Linked list' in C++

static_linked_list_demo.cpp

struct node{
  // A node has two components: some data and a pointer to the next node.
  int node_data;
  node* next;
};
 
int main(){
  // Make some nodes:
  node A,B,C;

  // Make a reference to the 'front' of the list
  node* start;
 
  // Make the list start at 'A'
  start = &A;
 
  // Create a link from 'A' to 'B'
  A.next = &B;

  // Create a link from 'B' to 'C'
  B.next = &C;
 
  // Give 'C' a special value to show it's the end of the list:
  C.next = NULL
 
  return 0;
}

good, basic code
