Which has more priority: || or && or ==
提问by Giovanni Genna
I have this expression:
我有这样的表达：
y[i] = ( z[i] == a && b || c )
Which of these elements (&&, ||, ==) have the priority?
哪些元素 ( &&, ||, ==) 具有优先级？
Can you please show the order of operations with brackets?
你能用括号显示操作顺序吗？
回答by André Chalella
First ==, then &&, then ||.
首先==，然后&&，然后||。
Your expression will be evaluated as y[i] = (((z[i] == a) && b) || c).
您的表达式将被评估为y[i] = (((z[i] == a) && b) || c)。
