    int b = 5;
    bool result;
    result = a < b; // true
    result = a > b; // false
    result = a <= 4; // a  is less than or equal to 4 - true
    result = b >= 6; // b is greater than or equal to 6 - false
    result = a == b; // a is equal to b - false
    result = a != b; // a is not equal to b - true
    result = a > b || a < b; // logical or operation. - true
    result = 3 < a && a < 6; // logical and operation. - true
    result = !result; //  not - false
