Develop the following class: Class Name: ImprovedArrayBasedStack Access Modifier: public Implements: ImprovedStackInterface Instance variables Name: top Access modifier: private Data type: int Name: stack Access modifier: private Data type: T[] (an array of parameterized type) Constructors Name: ImprovedArrayBasedStack Access modifier: public Parameters: none (default constructor) Task: sets the value of top to -1 sets the stack to refer to an array of Objects with 100 elements which are type cast to T[] Name: ImprovedArrayBasedStack Access modifier: public Parameters: size (data type int) Task: sets the value of top to -1 sets the stack to refer to an array of Objects with the number of elements equal to the size parameter which are type cast to T[] Methods Name: push Access modifier: public Parameters: item (data type T, parameterized type) Return type: void Throws: StackFullException Task: if the value of top is less than the length of the stack minus 1 then increase the value of top by 1 and place the item at the top of the stack, otherwise throw a StackFullException with the message "Not enough room for one item" Name: push Access modifier: public Parameters: item1 (data type T, parameterized type), item2 (data type T, parameterized type) Return type: void Throws: StackFullException Task: if the value of top is less than the length of the stack minus 2, then increase the value of top by 1 and place item1 at the top of the stack, then increase the value of top by 1 and place item2 at the top of the stack, otherwise throw a StackFullException with the message "Not enough room for two items" Name: pop Access modifier: public Parameters: none Return type: void Throws: StackEmptyException Task: if the value of top is greater than -1 then remove the item at the top of the stack by replacing it with null and decrease the value of top by 1, otherwise throw a StackEmptyException with the message "No item to remove" Name: doublePop Access modifier: public Parameters: none Return type: void Throws: StackEmptyException Task: if the value of top is greater than 0, then remove the item at the top of the stack by replacing it with null and decrease the value of top by 1, then remove the item at the top of the stack by replacing it with null and decrease the value of top by 1, otherwise throw a StackEmptyException with the message "There are less than two items in the stack" Name: top Access modifier: public Parameters: none Return type: T (parameterized type) Throws: StackEmptyException Task: if the value of top is greater than -1 then return the item at the top of the stack, otherwise throw a StackEmptyException with the message "Top attempted on an empty stack"

HW 8-1a  

1.)   Referring to the UML class diagram, create a program that utilizes the Student class.

- id : Integer

- units : Integer

- name : String

+ Student ( ) :

+ Student (id : Int, name : String, units : Int) :

+ ~Student( ) :

+ setID(id : Integer) : void

+ setName(name: String) : void

+ setUnits(units : Integer ) : void

+ displayRecord() : void

2.)   Include 3 files:

-   Source.cpp

-   Student.h

-   Student.cpp

3.)   In main(), declare two objects of Student type, named s1 and s2.

• The s1 object calls the default constructor.
  • For s1, the object should be instantiated (initialized) with these values:
    • ID: 0
    • Name: (empty string)
    • Units: 0
• The s2 object calls the overloaded constructor.
  • For s2, the object should be instantiated (initialized) with these values:
    • ID: 100
    • Name: Tom P. Lee
    • Units: 12

4.)   In main(), the s1 object calls its displayRecord() function. Here is the output:

           ID:        0

          Name:

           Units:     0

5.)   Then in main(), the s2 object calls its displayRecord() function. Here is the output:

           ID:        100

           Name: Tom P. Lee

           Units:     12

6.)   Then in main(), use the set functions to set to assign these values to the s1 object:

           ID:        101

           Name: John Lee Hooker

           Units:     15   

7.)    Finally, the s1 object calls its displayRecord() function again. Here is the output:

           ID:        100

           Name: John Lee Hooker

           Units:     15

/* OUTPUT

Here is student #1:

   ID:     0

   Name:  

   Units: 0

Here is student #2:

   ID:     100

   Name:   Tom P. Lee

   Units: 12

Here is student #1 after the set functions:

   ID:     100

   Name:   John Lee Hooker

   Units: 15

1) Referring to the following UML class diagram, create a program that utilizes three class specifications:

Student, UnderGrad, and Grad

- Include these 7 files in your project:

- main.cpp

- Student.h

- Student. cpp

- UnderGrad.h

- UnderGrad.cpp

- Grad.h

- Grad.cpp

2.)   In main(), declare two objects of UnderGrad and Grad type, respectively, as show below:

int main()

{

           UnderGrad underGrad(100, 9, "Tom Lee", "Freshman");

           Grad grad(101, 12, "Jim Jones", "PHD");

3.)   In main(), the object, underGrad, calls its displayRecord() function. Here is the output:

           ID:        100

           Name: Tom Lee

           Units:     9

           Class:     Freshman

4.)   In main(), the object, grad, calls its displayRecord() function. Here is the output

             of the function:

           ID:        101

           Name: Jim Jones

           Units:     12

           Degree:    PHD

5.)   Then, in main(), the object, grad, calls its setUnits() function, and changes the number of units

from 12 to 15.

6.)   Finally, in main(),the object, grad, calls its displayRecord() function. Here is the output

             of the function:

           ID:        101

           Name: Jim Jones

           Units:     15              ß (Units has changed to 15)

          Degree:    PHD

Please make a code on C++ language, and please add comments for each codes.

Surplus Warehouse purchased a forklift on January 1, 2016, for $12,000. The forklift is expected to last for five years and have a residual value of $1,200. Surplus Warehouse uses the double-declining-balance method for depreciation.

a. Calculate the depreciation expense, accumulated depreciation, and book value for each year of the forklift’s life. Round any depreciation calculations to the nearest dollar.
