Output:

a = 7
b = 0
c = -3

a && b : 0
a && c :1
a || b :1
a || c :1
!a : 0
!b :1
!(a != b) is :0
!(a == b) is : 1
(a == b) && (c > b) is :0
(a == b) && (c < b) is : 0
(a == b) || (c < b) is :1
(a != b) || (c < b) is : 1
(a != b) || (c < b) && (a < c) is :1
(a == b) || (c < b) && (a > c) is : 1
(a == b) && (c < b) || (a > c) is : 1
