WebThe two-arg version of the std::sort algorithm sorts the vector in ascending order using operator<. To get the descending order, make a call to std::reverse after std::sort. The above code requires an extra pass to reverse the vector. One can avoid the call to std::reverse by using reverse iterators. 2. Using std::sort + comparator. WebC++ Program – Sort Integer Array. To sort elements of an integer array, call sort () function and pass the beginning and ending of the array as arguments. By default, sort () function sorts the elements in ascending order.
