unordered_multimap max_load_factor() function in C++

The unordered_multimap::load_factor() function is a C++ STL built-in function that returns the current value of the load factor in the unordered_multimap container. The load factor is defined as the ratio of the total amount of components in a container (its size) to the total number of buckets (bucket_count):

load_factor = bucket_count / size

The load factor impacts the probability of a collision inside a hash table (i.e., the probability of two entries being in the same bucket). By inducing a rehash each time an expansion is required, the container dynamically raises the number of buckets to maintain the load factor below a certain threshold (its max_load_factor).

The unordered_multimap::max_load_factor() function is a standard C++ STL function that produces the maximum load factor of the unordered_multimap containers. This function also allows you to specify the maximum load factor.

Syntax:

It has the following function:

Functions: The function accepts no parameters.

Return Value: It provides an integral value indicating the container's maximum load factor.

Example:

Output:

The max load factor value is: 1
The key values of ex are:{6, 600} {5, 500}

Syntax:

The function receives a single necessary parameter, N, that indicates the load factor to be set. This N represents the container's maximum load factor.

Return Value: Nothing is returned by the function

Example:

Output:

The value of the load balancer: 1
The max load factor of the sample after setting it: 300
The elements of the sample {40, 400} {10, 300}
