Chapter 2, Problem 14SA
Explanation of Solution
Let us number the statements as follows:
(1) x = 7; y = 2 * x - 3;
(2) z = x + y - 3;
(3) x = z / y;
(4) y = z - x;
(5) w = x + y + 2 * z;
(6) w–;
(7) y = 2 * w + z - x;
The execution is explained in the table below. '?' indicates that the value is unknown.

Suppose x, y, z, and w are int variables. What value is assigned to each of these variables after the last statement executes? x = 7; y = 2 * x - 3;z = x + y - 3;
x = z / y;y = z - x;w = x + y + 2 * z;w--;y = 2 * w + z - x;
Assume x is 10, y is 7, and z;
x and y are int, z is bool.
What is assigned to z?
z = x < y
Q1\A) A paint company is trying to recycle unpopular paint colours by mixing them together
to create better colours. All paints are composed of four pigments (A,B,C,D). The current
paints are composed of pigments (in percent) according to the following equations: are p₁ =
80A + 16C + 4D, P2 = 80B + 20C, P3 = 30A + 10B + 60℃, p4 = 10A + 10B + 72C + 8D. The
better colour say p5 is composed as follows: p5 = 40A + 27B + 31C + 2D. How much of the
paints P1, P2, P3, and p4 should be used to make one gallon of p5. Hint: use (Ax=b).
B) Write a MATLAB program to transform temperature from Fahrenheit to Celsius, if the
temperature is (OF) and the formula is Celsius= (Fahrenheit-32)x5/9.

- 4 -A mathematician and discovered a number which have unique properties. As he is not decided any name to that number, so for the time being we call that number ‘Cuboid’. A unique property of Cuboid is that, if we break that number into individual units like breaking 153 into 1, 5 and 3 and take their individual cube, then the sum would be the same as original number being given. Your task is to ask the user an integer and print weather the digit entered is Cuboid or not. (Python program)arrow_forwardNeeds to be done in C# language. Problem Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient, the following data should be entered: • The number of days spent in the hospital• The daily rate• Hospital medication charges• Charges for hospital services (lab tests, etc.) The program should ask for the following data if the patient was an out-patient: • Charges for hospital services (lab tests, etc.)• Hospital medication charges The program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other function accepts arguments for out-patient information. Both functions should return the total charges.
