The ‘=’ is an operator in C++ STL which copies (or moves) an unordered_multiset to another unordered_multiset and unordered_multiset::operator= is the corresponding operator function. There are three versions of this function:
- The first version takes reference of an unordered_multiset as an argument and copies it to an unordered_multiset.
Parameters: The first version takes the reference of an unordered_multiset as argument.
- The second version performs a move assignment i.e it moves the content of an unordered_multiset to another unordered_multiset.
Parameters: The second version takes the r-value reference of an unordered_multiset as argument
- The third version assigns contents of an initializer list to an unordered_multiset.
Parameters: The third version takes an initializer list as argument.
Return Value: All of them return the value of this pointer(*this).
The following program illustrates unordered_multiset::operator= .
1 1 1 2 2 2 3 3 3 3 4 4 4 4 4 4 3 2 1 1 1 1 1 2 2 2 3 3 3 3 4 4 4 4 4
