Unordered_set provides two operators in C++ STL. These are: Syntax: 1. (unordered_set &lhs == unordered_set &rhs) 2. (unordered_set &lhs != unordered_set &rhs) These operators are discussed… Read More
The unordered_set::end() function is a built-in function in C++ STL which returns an iterator pointing to the past-the-end-element. This iterator does not directly point to… Read More
The ‘=’ is an operator in C++ STL which copies (or moves) an unordered_set to another unordered_set and unordered_set::operator= is the corresponding operator function. There… Read More
equal_range() in general returns range that includes all elements equal to given value. For unordered_set where all keys are distinct, the returned range contains at-most… Read More
The unordered_set::empty is a built-in function in C++ STL which is used to check if an unordered_set container is empty or not. It returns True… Read More
The unordered_set::max_size() is a built-in function in C++ STL, defined in <unordered_set.h> which returns maximum number of elements that an unordered_set container can hold(i.e the… Read More
The unordered_set::load_factor() is a built-in function in C++ STL which returns the current load factor in the unordered_set container. The load factor is the ratio… Read More
The unordered_set::erase() function is a built-in function in C++ STL which is used to remove either a single element or a group of elements ranging… Read More
The unordered_set::bucket_count() method is a builtin function in C++ STL which returns the total number of buckets present in an unordered_set container. The bucket is… Read More
The unordered_set::begin() method is a builtin function in C++ STL which is used to return an iterator pointing to the first element in the unordered_set… Read More
The unordered_set::bucket() method is a builtin function in C++ STL which returns the bucket number of a specific element. That is, this function returns the… Read More
The unordered_set::swap() method is a builtin function in C++ STL which is used to exchange values of two unordered_set containers. It swaps the element of… Read More
The unordered_set::reserve() method is a builtin function in C++ STL which is used to request capacity change of unordered_set. It sets the number of buckets… Read More
The unordered_set::hash_function() is a built-in function in C++ STL which is used to get hash function. This hash function is a unary function which takes… Read More
