备注

The | operator looks at the binary representation of the values of two expressions and does a bitwise OR operation on them. The result of this operation behaves as follows:

0101  (expression1) 
1100  (expression2) 
---- 
1101  (result)

Any time either of the expressions has a 1 in a digit, the result will have a 1 in that digit. Otherwise, the result will have a 0 in that digit.
