Examples of problems evaluating Boolean expressions in C++

(1) Given the following declaration with initialization
statements:

int i = 15;
char ch = 'P';
bool test = true;
Text greet = "Hi";

what are the values of the following Boolean expressions:

(0 < i) && (i < 20)

(i == 0) || (i == 15)

!(ch <= 'Z')

test && !test

(greet != "Hi") && (greet != "Ho")


(2) Given that the integers i, j and k have the values 2, -4 and 7
what are the values of the following Boolean expressions:

(i < j) && (j < k)

(i < j) || (j < k)

(i < j) || ((j == k) && (!(j > k)))

(j < i) && !(i < j)

(i < j) || !(i < j)
