Web32. max_size () is the theoretical maximum number of items that could be put in your vector. On a 32-bit system, you could in theory allocate 4Gb == 2^32 which is 2^32 char values, 2^30 int values or 2^29 double values. It would appear that your implementation is using that value, but subtracting 1. Of course, you could never really allocate a ...

WebIntroduction to C++ Max Function. In C++, max is a function that is used to get the largest among the elements. In order to achieve that, there are different ways such as comparing two elements passed as arguments and returning largest among them, comparing two elements with the help of a binary function and passing it as an argument in std::max(), …
WebThe STL module of C++ provides a function max_element(). It accepts a range i.e. start & end iterators as arguments, and returns an iterator pointing to the largest value in the given range.
