Chapter 2.4, Problem 2.54PP

Practice Problem 2.54 (solution page 160)

Assume variables x, f, and d are of type int, float, and double, respectively. Their values are arbitrary, except that neither f nor d equals +∞, –∞, or NaN. For each of the following C expressions, either argue that it will always be true (i.e.,evaluate to 1) or give a value for the variables such that it is not true (i.e., evaluates to 0).

A. x == (int)(double) x
B. x == (int) (float) x
C. d == (double)(float) d
D. f == (float)(double) f
E. f == -(-f)
F. 1.0/2 ==1/2.0
G. d*d >=0.0
H. (f+d)-f == d
