Module Hierarchy Chart

The hierarchy chart is a graphical representation that is used to represent the relationship between various modules or systems in an organization. In programming, a hierarchy chart is used for representing an organizational framework. The hierarchy charts can also be utilized to show an organization’s reporting structure. In such a hierarchy chart, the President is at the top, the Vice Presidents are on the next level which is lower than its predecessor, and so forth.

(Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:
(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.
Create a new C# project then write a code equivalent to solve the problem given below. Create a menu driven program that will perform the following operations specified below. The program shall request data needed and display the result accordingly. Operations: - ADD NEW DATA - INSERT DATA - UPDATE DATA - DELETE DATA - RESET - SHOW DATA - EXIT Operations: - ADD NEW DATA – request single data from the user and store to arraylist - INSERT DATA – request index location and data to be inserted - UPDATE DATA – request index location and data to be updated - DELETE DATA – request data to be deleted - RESET – clear or reset the elements of arraylist - SHOW DATA – display all the elements of arraylist in horizontal manner - EXIT – end the execution of the program
C++A new video store in your neighborhood is about to open. However, it does not have a program to keep track of its videos and customers.

Problem Statement The barcode used by the U.S. Postal System to route mail is defined as follows: Each decimal digit in the ZIP code is encoded using a sequence of three half-height and two full-height bars. The barcode starts and ends with a full-height bar (the guard rail) and includes a checksum digit (after the five-digit ZIP code or ZIP + 4), computed by summing up the original digits modulo 10. Define the following functions: Draw a half-height or full-height bar on stddraw. Given a digit, draw its sequence of bars. Compute the checksum digit. Also define global code that read in a five- (or nine-) digit ZIP code as the command-line argument and draws the corresponding postal barcode.
