(TCO 3) What is the output of the following code snippet?


int a = 9, b = 4, c = -1;
if (a > b || (c = a) > 0)
{
cout << "TRUE" << a << b << c;
} else {
cout << "FALSE" << a << b << c;
}

(Points : 5)
FALSE 9 4 9
TRUE 9 4 -1
TRUE 9 4 -1
None of the above

(TCO 4) Why is this code snippet an infinite loop?

char answer = 'y';
while (answer == 'y' || answer = 'Y')
{
cout << "Still in loop" << endl;
cout << "Continue? (y for yes, n for no)" << endl;
cin >> answer;
}
(Points : 5)
The first line sets the value of answer to 'y' and, once the loop is entered, can never be changed
It is a sentinel-controlled loop, but the user is never asked to enter data.
The test expression always evaluates to TRUE because the value of the right-hand expression is the ASCII code for Y, which is non-zero, and anything other than zero is TRUE.
None of the above: it is not an infinite loop; it repeats until the user enters anything other than the letter y (either upper or lower case).

Explanation / Answer

a) TRUE 9 4 -1 b) beta = 14 c) while d) 26 e) continue f) None of the above: it is not an infinite loop; it repeats until the user enters anything other than the letter y (either upper or lower case).
