C Program to Demonstrate Logical Operators

Write C Code to demonstrate the use of logical operators

//Write a c program to demonstrate logical operators

    ans = a && b;      //logical and

    ans = a && c;      //logical and

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
