Anyway explain the below code..how the output became 0 -1 0

Question

{
int a =-1,b=-1,c;
c=++a&&b++;

cout << a<<endl<<b<<endl<<c;
}

output---->
0
-1
0

Answer 1

++a&&b++
a is incremented by 1
a=0
0 is false so the whole statement would be false
So the other side (b++) is skipped
b is still -1 and c is set to 0
