Question
Examine ways to output results using output statements Do the following problems. For assignment submission, use the format listed in the syllabus. Problem 01-4.5 points Evaluate the following expressions. a. 28 - 3 + 6 b. 6/5 c. 3*6/2 - 15 d. 4 - 6% 11 e. 37/4.0 f. 15 + 18% 2 - 20/6 g. 32 % 12 + 6 - 36/5 * 8 h. 5/9 * (32.6 - 4.5) i. 18.0 + 5.0* 3.0/4.0 Problem 02-2 points Suppose x, y, z, and w are int variables. What value is assigned to each of these variables after the last statement executes? x = 12: y = 18: z = x - 5/x: x = z - y: y = x + 3 * z: w = x - y + 2 * z: w++: z = 2 * y + w - x;Explanation / Answer
Evaluating the expressions:
A common technique we need to remember a abbrevations PEMADS.
1. Paraentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
a. 28-3+6
= 25+6 (from left to right)
= 31
b. 6/5 = 1.2
c. 3*6 / 2-15
18/2-15
9 - 15 = -6
d. 4-6 % 11
4- 66/100
4 - 0.66 = 3.34
e. 37/ 4.0 = 9.25
f. 15 + 18 % 2 - 20/6
15 + 36/100 - 20/6
15 + 0.36 - 3.33
15.36-3.33 = 12.03
h. 5/9 * (32.6 - 4.5 )
5 / 9 * 28.1
0.55 * 28.1 = 15.61
i 18.0 + 5.0 * 3.0 / 4.0
18.0 + 15.0 / 4.0
18.0 + 3.75 = 21.75
------------------------------------------------------------------------------------------------------
X = 12; Y = 18
Z = X - 5 / X;
= 12 - 5 / 12
= 12 - 0416
= 11.583
X = Z - Y
= 11.583 - 18
= -6.417
Y = X + 3 * z
= -6.417 + 3 * 11.583
= -6.417 + 34.749
= 28.332
W = X - Y + 2 * Z
= -6.417 - 28.332 + 2 * 11.583
= -6.417 - 28.332 + 23.166
= -34.749 + 23.166
= - 11.583
W++ = -10.583
Z = 2 * Y + W - X
= 2 * 28.332 + -10.583 - -6.417
= 56.664 - 10.583 + 6.417
= 46.08 + 6.417
= 52.497
So final values are
x = -6.417
y = 28.332
z = 52.497
w = -10.583
