Assignment Operator

 

• A = B : stores the value of B into A;
• A op= B :applies op to A and B, storing the result in A.

• A is a modifiable value expression, whose type is not qualified as const;
• op is any operator that can be used as an assignment operator ; B is an expression;

• In the first expression, if B is one of the basic data types (except void), it is converted to match the type of A.
• If A is a pointer, B must be a pointer to the same type as A, a void pointer, or the null pointer.
• If A is a void pointer, B can be of any pointer type.
• The second expression is treated as follows;

                          A = A op (B)
