1) Determine whether the following conditions are true or false. Assume that the
following variables have been declared and given the values shown.
double a = 5.0, b = 10.0, k = 2.0;
a != 3.0 – k
a + b >= 6.5
a > 10 || a < 6
!(k < 10)
2) Given the values for the int variables a and b, what is the output of the following program segments?
A) a = 5; b = 5;
if (a = = b && a > 0)
cout << "alpha";
cout << "gamma";
A) Output:
C) a = 0; b = 0;
if (a = = b && a > 0)
cout << "alpha";
cout << "gamma";
C) Output:
B) a = 5; b = 5;
if (a = = b)
if (a<0)
cout << "alpha";
else
cout << "gamma";
B) Output:
D) a = 5; b = 5;
if (a = = b)
if (a>0)
cout << "alpha";
else
cout << "gamma";
D) Output:
3) which is true when both a & b are zero, false otherwise
a) (a = = 0) && (b = = 0)
b) (a = = 0) | | (b = = 0 )
c) (a ! = 0) | | (b ! = 0 )
d) (a ! = 0) && (b ! = 0 )
4) Which expression selects the condition that the four variables a, b, c and d are the
same.
a) (a = = b && b = = c && c = = d)
b) (a = = b || b = = c || c = = d)
c) (a != b && b != c && c ! = d)
d) ! (a = = b || b = = c || c = = d)
5) Suppose you have two variables, a and b.
condition that none of the variables is zero:
a)
(a = = 0 || b = = 0 )
b)
(a = = 0 && b = = 0 )
c)
(a ! = 0 && b ! = 0 )
d)
(a ! = 0 || b ! = 0 )
Which expression will select the
