Let's say I have a C library that implements the following function: // Returns the number of elements in the array, // and a pointer to the first element. // The memory pointed to has static lifetime. size_t MyLib_GetValues (const int** outBasePtr); WebA pointer, pointing to the start of array i.e. arr. A pointer pointing to the middle of the array i.e. arr + len/2.Where, len is the size of array. A reverse iterator pointing to the end of array i.e. std::reverse_iterator(arr + len). The std::equal() function will compare the first half of the array, with the second half of array, but in the reverse direction because we have … how do i add photo to teams
