Chapter 2.4, Problem 2.16CP
Explanation of Solution
Variables:
A memory space, which contains a data value, is called as variable.
- The variable must be declared before it is used in the program, because Java
programming language statically typed. - The variable name should begin with a character, underscore (_) or dollar sign ($) and they should not start with a number.
- N number of variables can be defined in a single declaration statement.
- Variable names are case sensitive; a variable name with uppercase letter is different from the variable name with lower case letters...

Believed to have originated in France, a gradian is a unit of measure of an angle that is equivalent to 1/400th of a turn or 9/10th of a degree. The formula for this conversion solving for Gradian is: Gradian = 400 * turn or Gradian = 1.111 * degreePrompt the user for a value and displays the Gradian value you calculate, if the original value was a degree or a turn. A sample program dialogue is shown below.What's your number: 10.0Assuming you entered a turn amount, here's your Gradian: 4000.000Assuming you entered a degree amount, here's your Gradian: 11.110What's your number: 15.12Assuming you entered a turn amount, here's your Gradian: 6048.000Assuming you entered a degree amount, here's your Gradian: 16.798

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 inpatient or an outpatient. If the patient was an inpatient, the following data should be entered:
The number of days spent in the hospital
The daily rate
Charges for hospital services (lab tests, etc.)
Hospital medication charges
If the patient was an outpatient, the following data should be entered:
Charges for hospital services (lab tests, etc.)
Hospital medication charges
Use a single, separate function to validate that no input is less than zero. If it is, it should be reentered before being returned. Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient data. Both functions should return the…
Assume the variable sales references a float value. Write a statement that displays the value rounded to two decimal points.

- Answer this question Write a program that calculates and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:BMI = weight × 703 / height2where weight is measured in pounds and height is measured in inches. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person’s weight is considered to be optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered to be underweight. If the BMI value is greater than 25, the person is considered to be overweightarrow_forwardTrue or False 3. Variable names can have spaces in themarrow_forwardA complex number is a number in the form a + bi, where a and b are real numbers and i is sqrt( -1). The numbers a and b are known as the real part and imaginary part of the complex number, respectively.You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas:a + bi + c + di = (a + c) + (b + d)ia + bi - (c + di) = (a - c) + (b - d)i(a + bi) * (c + di) = (ac - bd) + (bc + ad)i(a+bi)/(c+di) = (ac+bd)/(c^2 +d^2) + (bc-ad)i/(c^2 +d^2)You can also obtain the absolute value for a complex number using the following formula:| a + bi | = sqrt(a^2 + b^2)(A complex number can be interpreted as a point on a plane by identifying the (a, b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in Figure 13.10.)Design a class named Complex for representing complex numbers and the methods add, subtract, multiply, divide, and abs for performing complex…arrow_forward
