Answer to Question #303687 in C++ for Imzi

Question

2. Suppose that x, y, and z are int variables, and x = 10, y = 15, and z = 20. Determine

whether the following expressions evaluate to true or false:

a. !(x > 10)

b. x <= 5 || y < 15

c. (x != 5) && (y != z)

d. x >= z || (x + y >= z)

e. (x <= y - 2) && (y >= z) || (z - 2 != 20)

3. Rewrite the following expressions using an if...else statement. (Assume that all variables

are declared properly.)

a. (x < 5) ? y = 10 : y = 20;

b. (fuel >= 10) ? drive = 150 : drive = 30;

c. (booksBought >= 3) ? discount = 0.15 : discount = 0.0;

Answer 1

2.

a. true

b. false

c. true

d. true

e. true

3.

a. if (x < 5) y = 10; else y = 20;

b. if (fuel >= 10) drive = 150 ; else drive = 30;

c. if (booksBought >= 3) discount = 0.15 ; else discount = 0.0;
