2. How do I use arrays in C++? - Stack Overflow

   stackoverflow.com/questions/4810664

   In C, anonymous arrays are created via malloc and friends. In C++, anonymous arrays are created using the new T[size] syntax which returns a pointer to the first element of an anonymous array: std::size_t size = compute_size_at_runtime(); int* p = new int[size];

3. c++ - How do I find the length of an array? - Stack Overflow

   stackoverflow.com/questions/4108313

   array<type_of_the_array, number_of_elements_in_the_array> Name_of_Array = {}; So now if you want to find the length of the array, all you have to do is using the size function in the array class. Name_of_Array.size(); and that should return the length of elements in the array. edited May 25, 2020 at 23:07.

4. c++ - Correct way to work with vector of arrays - Stack Overflow

   stackoverflow.com/questions/4612273

   You cannot store arrays in a vector or any other container. The type of the elements to be stored in a container (called the container's value type) must be both copy constructible and assignable. Arrays are neither. You can, however, use an array class template, like the one provided by Boost, TR1, and C++0x: std::vector<std::array<double, 4> >.

5. c++ - Return array in a function - Stack Overflow

   stackoverflow.com/questions/3473438

   C++ functions can't return C-style arrays by value. The closest thing is to return a pointer. Furthermore, an array type in the argument list is simply converted to a pointer. int *fillarr( int arr[] ) { // arr "decays" to type int * return arr; }

6. How to dynamically allocate arrays in C++ - Stack Overflow

   stackoverflow.com/questions/35532427

   type_name *variable_name = new type_name; The arrays are nothing but just the collection of contiguous memory locations, Hence, we can dynamically allocate arrays in C++ as, type_name *array_name = new type_name[SIZE]; and you can just use delete for freeing up the dynamically allocated space, as follows, for variables, delete variable_name;

7. How to declare an array of strings in C++? - Stack Overflow

   stackoverflow.com/questions/34987

   Also, because of the way arrays are passed to functions (converted to a pointer to the first element), it doesn't work across function calls even if the signature looks like an array — some_function(string parameter[]) is really some_function(string *parameter).

8. c++ - Arrays vs Vectors: Introductory Similarities and...

   stackoverflow.com/questions/15079057

   I'll add that arrays are very low-level constructs in C++ and you should try to stay away from them as much as possible when "learning the ropes" -- even Bjarne Stroustrup recommends this (he's the designer of C++). Vectors come very close to the same performance as arrays, but with a great many conveniences and safety features.

9. How do I declare a 2d array in C++ using new? - Stack Overflow

   stackoverflow.com/questions/936687

   But still std array are one dimensional array, like the normal c++ arrays. But thanks to the solutions that the other guys suggest about how you can make the normal c++ one dimensional array to two dimensional array, we can adapt the same ideas to std array, e.g. according to Mehrdad Afshari's idea, we can write the following code:

10. creating an array of structs in c++ - Stack Overflow

    stackoverflow.com/questions/6810656

    vector<Customer> array_of_customers; By using vector, you will have more freedom and access in the array of structure. Now if want to add an struct element in the define array. You can use. array_of_customer.push_pack(/* struct element here */) Example: Customer customer1; customer1.uid = 01; customer1.name = "John Doe";

11. c++ - How do you assign all elements of an array at once ... -...

    stackoverflow.com/questions/5732798

    There is a difference between initialization and assignment. What you want to do is not initialization, but assignment. But such assignment to array is not possible in C++. Here is what you can do: #include <algorithm>. int array [] = {1,3,34,5,6}; int newarr [] = {34,2,4,5,6}; std::ranges::copy(newarr, array); // C++20.
