CodePudding user response:

C the logic operation is short circuit operation, so y=2, no execution;

CodePudding user response:

& & : x=0, while in parentheses and x==1 at this time was not false, false, y=2 behind this statement is not performed, because & amp; & As long as there is a statement which is false, that this expression is false, is not to judge the statements on the right, so y is 0
