Array indices are zero-based because the first element is at offset zero from the start of the array. There is no such thing as a one-based array in C. Some other languages do allow you to specify the base of an array, but converting a non-zero-based index to a zero-based index adds a runtime overhead to the implementation.

Can Array-based lists can never be empty?
It's either an array or it's a list, it cannot be both. However, an empty array is entirely possible: std::vector<int> my_vector; // an empty array my_vector.push_back(42); // an array of 1 element my_vector.push_back(1); // an array of 2 elements my_vector.clear(); // an empty array An empty list is also possible: std::list<int> my_list; // an empty list my_list.push_back(42); // a list of 1 element my_list.push_back(1); // a list of 2 elements my_list.clear(); // an empty list The same thing can be done in C: int* my_array = nullptr; // an empty array my_array = malloc (2*sizeof(int)); // an array of 2 elements my_array[0] = 42; my_array[1] = 1; free my_array; // an empty array my_array = 0;
Two linked list in a array is possible?
Like this: #define MAXLIST 100 int first, next [MAXLIST]; /* let the list be: #0 ---> #2 ---> #1 */ first= 0; next[0]= 2; next[2]= 1; next[1]= -1; /* means end of list */ Note: you should track which elements are unused, in the beginning every elements are unused: int first_unused= 0; for (i= 0; i<MAXLIST; ++i) next[i]= i+1; next[MAXLIST-1]= -1; /* means end of list */

How do you swap two adjecent no in array in c?
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
