Program Description Answer

One of the example of decision structure is “if” statement.

Hence, the correct answer is option “B”.

Explanation of Solution

Decision structure:

Sequence structure cannot handle all types of tasks. These can be achieved using decision structure. Example: “if” statement.

“if” statement:

“if” statement is used to make a decision structure, which permits the program to hold more than one path of execution.

  • The indented statement is executed only when the condition is “true”.
  • If the given condition is “false”, it skips the indented statements.

Syntax for “if” statement:

if condition:

indented_statement_block

Explanation for incorrect options:

Sequence Structure:

Simplest form of control structure is the “sequence structure”. It is a group of statements that are executed in the order in which they appear.

Hence, the option “A” is wrong.

Pathway Structure:

Pathway structure does not execute the statements under certain conditions.

Hence, the option “C” is wrong.

Class Structure:

Class structure is defined as a hierarchical organization where a community is divided into classes.

Hence, the option “D” is wrong.

Restaurant: Point-of-Sales System Create a software application that can be used for a Restaurant using C language. The expected minimum functionality are as follows: Menu Display  It must display at least 10 choices with their corresponding prices On your menu, at least one of the categories/choice should have customization/add-on. You should have at least 3 customization/add-on (e.g. In Starbucks, you can have extra espresso shot). Taking Orders As a customer, I want to select which of the choices I want to order As a customer, everytime I specify select my choice, I want to specify the quantity of my selected choice. After I finished my order, it should ask, "Anything Else?". Afterwards, as a customer, I should be to enter my succeeding choice. In order to stop taking order, the exit should be part of the menu. As a customer, I would only select that choice to exit If the customer selects a choice qualified for customization, after specifying the quantity, I should be asked,…
Programing language is C# 6. Hospital Charges Create an application that calculates the total cost of a hospital stay. The daily base charge is $350. The hospital also charges for medication, surgical fees, lab fees, and physical rehab. The application should accept the following input: • The number of days spent in the hospital • The amount of medication charges • The amount of surgical charges • The amount of lab fees • The amount of physical rehabilitation charges Create and use the following value-returning methods in the application: • CalcStayCharges—Calculates and returns the base charges for the hospital stay. This is computed as $350 times the number of days in the hospital. • CalcMiscCharges—Calculates and returns the total of the medication, surgical, lab, and physical rehabilitation charges. • CalcTotalCharges—Calculates and returns the total charges.
GPA Calculator Students are concerned about their GPA. They need to calculate it accurately every semester to monitor their progress. Develop a GPA calculator that follows the AOU regulations (AOU-OU Grade Scale) using C# programming language. The application asks the student to enter his numeric grade of each course and the course's credit hours. Accordingly, the application calculates the student's GPA after converting the numeric grade to letter grade. The GPA calculation should produce floating-point results. Display the results rounded to the nearest hundredth. You should store the letter grades of all student's courses in an array. The final grade of the student should be also calculated. Sample I/O Enter the course grade (-1 to end): 93 Enter the course credit hours: 3 Enter the course grade (-1 to end): 74 Enter the course credit hours: 2 Enter the course grade (-1 to end): 60 Enter the course credit hours: 3 Enter the course grade (-1 to end): -1 The grades of your courses…
