After the assignment, an assignment expression has the value of the left operand but is not an l-value.In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place.Tags: How Do You Learn Critical ThinkingJesus And Salvation An Essay In InterpretationEssay On Analyzing An ArgumentNarrative Thesis CreatorMla Note Card Research PaperSqa Intermediate 2 Maths Past PapersWrite Critical Essay ThesisOthello EssaysValue Of Responsibility EssayA Very Short Essay On Friendship
However, the operator is usually defined to return a reference to the assignee.
This is consistent with the behavior of assignment operator for built-in types (returning the assigned value) and allows for using the operator invocation as an expression, for instance in control statements or in chained assignment.
Also, the C Standard Library requires this behavior for some user-supplied types.
A relational operator checks the relationship between two operands.
A implicitly-declared copy assignment operator for class .
All data types compatible with the C language (POD types) are trivially copy-assignable.
See assignment operator overloading for additional detail on the expected behavior of a user-defined copy-assignment operator.
they are members of the same union), the behavior is undefined unless the overlap is exact and the types are compatible.
If only the copy assignment is provided, all argument categories select it (as long as it takes its argument by value or as reference to const, since rvalues can bind to const references), which makes copy assignment the fallback for move assignment, when move is unavailable.
It is unspecified whether virtual base class subobjects that are accessible through more than one path in the inheritance lattice, are assigned more than once by the implicitly-defined copy assignment operator (same applies to move assignment).
