What is an ordered list of data structure using c plus plus?
An ordered list of data in any programming language is simply a sorted array or list. In C++ this can either mean a sorted array, vector, list or forward list.
C plus plus array-based lists?
If you mean an array where each element is a list, then the STL is your friend. To create an array of lists of any type T, use the following declaration: std::vector<std::list<T>> my_array_of_lists;
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;
Difference between vector and list in c plus plus?
Although they share many of the same features, there are many differences. For instance, a list does not have an index operator [] while a vector does not have a merge method. If in doubt, simply look at the variable's declaration -- it will explicitly state whether the variable is a list or a vector (or indeed some other STL container), along with the type of data that it contains. Ultimately a vector is just an array, ideally suited to random access, whereas a list is ideally suited to sequential access.
Is it the most efficient approach to access elements with the vector data structure?
Yes. A vector is a variable-length array but constant-time random-access is guaranteed regardless of an array's length.
Main difference between Array List and Vector in Java?
List is not sync'd as a vector is.
Difference between vector and array list?
Vectors are thread safe but array lists are not. Hence array lists are faster than Vectors.

C plus plus array-based lists?

What do string and vector and array all inherit from that has the size method so you can take it as an argument?
string, vector and array do not have a common base class. Overload your function to accept either a string, a vector or an array.
What is a array in math?
An array is a computer science equivalent of a vector in mathematics. Both contain a list of data.
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;
What is the use of vector class. Explain how it is different from an array?
Vector class is defined inside util package this is differing form an array in a fashion that arrays size can not be changed during run time so as to have an object that might contain list of values and should facilitate programmer to extend or shrink the size of a data structure as and when required Vector should be used.

Why is an array called a derived data type?
An array is not a derived data type at all. In order to be derived there has to be a base class and an array has no base class. Here is the basic declaration of the std::array template class from the <array> header file: template<class _Ty, size_t _Size> class array { // fixed size array of values // ... }; A vector, on the other hand, is derived (from the <vector> header file): template<class _Ty, class _Alloc = allocator<_Ty>> class vector : public _Vector_alloc<!is_empty<_Alloc>::value, _Vec_base_types<_Ty, _Alloc>> { // varying size array of values // ... };
What are numbers lined up horizontally called?
A horizontal array or a row vector.
