Currently skim through about c++, but at below example my brain stuck.

at the `res`

variable, example have preincrement of `a`

,`b`

and `c`

integer values.

When I print it out first one have output of `a = 1, b = 0, c=0`

at the second part output is `a = 1, b = 0, c=0`

```
int a, b, c;
a = 0;
b = 0;
c = 0;
res = ++a || ++b && ++c;
cout << 'n'
<< " res = " << res
<< ", a = " << a
<< ", b = " << b
<< ", c = " << c << endl;
a = b = c = 0;
res = ++a && ++b || ++c;
cout << " res = " << res
<< ", a = " << a
<< ", b = " << b
<< ", c = " << c << endl;
```

both of them I’m expecting output as `a = 1, b = 1, c=1`

because I have already incremented variables.

From output I understand if after `||`

operator, nothing is evaluated? I need clarification. Thanks.
