Although arrays are not assignable, an array wrapped in a struct is assignable to another object of the same (or compatible) struct type.
Also, the C Standard Library requires this behavior for some user-supplied types.
A relational operator checks the relationship between two operands.
An assignment operation assigns the value of the right-hand operand to the storage location named by the left-hand operand.
Therefore, the left-hand operand of an assignment operation must be a modifiable l-value.
If the implicitly-declared copy assignment operator is neither deleted nor trivial, it is defined (that is, a function body is generated and compiled) by the compiler if odr-used.
For ), the operator performs member-wise copy assignment of the object's bases and non-static members, in their initialization order, using built-in assignment for the scalars and copy assignment operator for class types.Unlike in C , assignment operators in C# cannot be overloaded directly, but the user-defined types can overload the operators like , -, /, etc.This allows the assignment operator to be used with those types.The copy assignment operator, often just called the "assignment operator", is a special case of assignment operator where the source (right-hand side) and destination (left-hand side) are of the same class type.It is one of the special member functions, which means that a default version of it is generated automatically by the compiler if the programmer does not declare one.If the relation is true, it returns 1; if the relation is false, it returns value 0.Relational operators are used in decision making and loops.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.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.
