Program Plan Intro

Program plan:

BarChartWithPositiveNegative.java

Create a class named “BarChartWithPositiveNegative”.

Define a function named “readinputValues”.

Create an ArrayList object called “listofarr”, which will store integer values.

Using “while(in.hasNextInt())” loop, read all input values and add elements to the array list using “add()” method .

Return “listofarr”.

Define an “int” function named “findMaxElement”.

Declare an integer variable named “maxval” and access the list using “get()” method.

Using enhanced “for” loop, iterate and find the maximum value in the array list.

Inside the loop, the conditional statement “if” checks whether “a” is greater than “maxval” or not

If the condition is true, the maximum value will be stored in the variable “maxval”

Return “maxval”.

Define an “int” function named “findMinElement”.

Declare an integer variable named “minval” and access the list using “get()” method.

Using enhanced “for” loop, iterate and find the maximum value in the array list.

Inside the loop, the conditional statement “if” checks whether “b” is greater than “minval” or not

If the condition is true, the maximum value will be stored in the variable “minval”

Return “minval”.

Define a function named “printBarChartforposneg”.

Declare an integer variable named “maximum” and call the function “findMaxElement”.

Declare an integer variable named “minimum” and call the function “findMinElement”.

Initialize “posAsterisk” as “40”.

Initialize “negAsterisk” as “0”.

Using “if” conditional statement, check whether the “Math.abs(minimum)” is greater than “maximum” or not.

If the condition is true, assign the value “40” into variable “negAsterisk” and then compute positive asterisks and store into the variable “posAsterisk”.

Else if check whether the minimum value is less than “0” or not and then compute negative asterisk and store into variable “negAsterisk”.

Using “for” loop, print and generate the bar chart.

Inside the “for” loop, using “get()” method retrieve a number from the values and store into the variable “num”.

Using the “if” conditional statement, check whether the “num” is greater than “0” or not.

If the condition is true, compute the number of asterisks and store into the variable “asterisks”.

Using “for” loop, print empty spaces for negative asterisks on the screen.

Using “for” loop, print asterisks on the screen.

Else, it computes the number of asterisk and stores it into the variable “asterisks”.

Using “for” loop, print spaces for the negative asterisks.

Using “for” loop, print asterisks on the screen.

Define a main function.

Declare an array list variable named “Arrlist” and call the function “readinputvalues” to read a sequence of positive and negative values.

Call the function "printBarChartforposneg" and pass “Arrlist” as parameter for displaying the bar chart of asterisks based on the input list and maximum and minimum values in the array list.

Objective: 1. Implement a custom Vector class in C++ that manages dynamic memory efficiently. 2. Demonstrate an understanding of the Big Five by managing deep copies, move semantics, and resource cleanup. 3. Explore the performance trade-offs between heap and stack allocation. Task Description: Part 1: Custom Vector Implementation 1. Create a Vector class that manages a dynamically allocated array. 。 Member Variables: ° T✶ data; // Dynamically allocated array for storage. std::size_t size; // Number of elements currently in the vector. std::size_t capacity; // Maximum number of elements before reallocation is required. 2. Implement the following core member functions: Default Constructor: Initialize an empty vector with no allocated storage. 。 Destructor: Free any dynamically allocated memory. 。 Copy Constructor: Perform a deep copy of the data array. 。 Copy Assignment Operator: Free existing resources and perform a deep copy. Move Constructor: Transfer ownership of the data array…

Hi-Volt Components You are the IT manager at Hi-Voltage Components, a medium-sized firm that makes specialized circuit boards. Hi-Voltage's largest customer, Green Industries, recently installed a computerized purchasing sys- tem. If Hi-Voltage connects to the purchasing system, Green Industries will be able to submit purchase orders electronically. Although Hi-Voltage has a computerized accounting system, that system is not capable of handling EDI. Tasks 1. What options does Hi-Voltage have for developing a system to connect with Green Industries' pur- chasing system? 2. What terms or concepts describe the proposed computer-to-computer relationship between Hi-Voltage and Green Industries? why not? 3. Would Hi-Voltage's proposed new system be a transaction processing system? Why or 4. Before Hi-Voltage makes a final decision, should the company consider an ERP system? Why or why not?
