How can we write a program which orders the elements of a board given there language of programming c plus plus?

Answer 1

In C++ you can use the standard library sort algorithm to sort any data sequence provided the elements support the appropriate comparison operator (std::less<T> for any given type T is used by default).

For example:

std::vector<int> v {5, 9, 7, 1, 3};

std::sort (v.begin(), v.end()); // v = {1, 3, 5, 7, 9}

std::sort (v.begin(), v.end(), std::greater<int>); // v = {9, 7, 5, 3, 1}
