WebFeb 13, 2024 · An array is a sequence of objects of the same type that occupy a contiguous area of memory. Traditional C-style arrays are the source of many bugs, but are still common, especially in older code bases. In modern C++, we strongly recommend using std::vector or std::array instead of C-style arrays described in this section. WebJan 11, 2024 · We can pass “greater ()” function to sort in descending order. This function does comparison in a way that puts greater elements before.
