Question
Chapter 2.6, Problem 2.9CP
- A)
Program Plan Intro
Data types:
The variables use data-type during their declaration.
- The data-type is used to determine the size of memory allocated. Here, the compiler allots the memory.
- All data-type needs different size of memory.
Some of the data-types are:
- Integer
- Boolean
- Character
- Double
- Floating point
From the table 2-6:
Variable to hold numbers in the range from 32 to 6,000
From the table 2-6, “short” or “unsigned short” data-type hold numbers in the range from 32 to 6,000.

From the table 2-6:
Literal which uses more memory
From the given literal “20” and “20L”; both the literals uses same amount of memory because both the “int” and “long int” data-types size are 4 bytes.

Question 1
You have to define the data type declaration for a variable that will store a string of text of 100 characters.
You will be referencing the variable as a string and not as a series of individual characters.
Assume the variable is called strText.
What is the data definition for the variable?
C1.
Write an assignment that assigns to a variable named red_change the percentage change in the red level if red were updated to be 128.
(Hint: use floating point division)
C2.
Write an assignment that assigns a variable named new_blue so that it contains the blue value (as a float), assuming the new_blue value is equivalent to blue increased by 25 percent.

Language is C. Please answer as simply as you can. Thank you! Write two functions, main and question_1. The main function is the start of your program, and question_1 passes in a double and and a pointer of an integer. question_1 does not have a return type. In the main function, create an integer with the value of 8. Call question_1 and pass in the value 5.75 as the double and the value of the integer. Afterwards print out the be value of the integer. In the function question_1, add the double value to the integer. HINT: You will need to cast the double in order to add them together. When running this program, your end result should print out the value 13. Don't trick the program to just print 13, because there is no points assigned here, instead all the points are in the process of getting to 13.arrow_forward

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.
