Comment on the following expression? c = (n) ? a : b; can be rewritten as
1.if (!n)c = b; else c = a
2.if (n <= 0)c = b; else c = a
3. if (n > 0)c = a; else c = b;
4.All of the mentioned

For initialization a = 2, c = 1 the value of a and c after this code will be c = (c) ? a = 0 : 2;
1.a = 0, c = 0;
2.a = 2, c = 2;
3.a = 2, c = 2
4. a = 1, c = 2;
