You are required to implement a shopping cart module for an online shopping mall. From the available
items a user will select the item to purchase and add this into his shopping cart. Before the checkout
customer can remove any item from the cart at any time.
A single item in the cart contains the following details:
class Item
{
private:
int itemID;
string itemName;
double price;
double purchasedQuantity;
double totalPrice;
public:
//constructors and getter setters
};
For the implementation of the required module you have to meet the following requirements:
1- Customer can add any item to the cart in desired quantity.
Remember if customer added the same item in the cart again, your implementation will not add
this as a new item it will check if the item already exists than it will just add the new quantity in
the previous and update other data.
Create a program that uses an array of structures of a user-defined type named student_record as shown in the declaration below.
struct student_record{
unsigned long id;
char name[20];
char subject[20];
double mt_grade;
double ft_grade;
double final_rating;
char remarks[20];
};
2. The program should ask how many student records to input (at least 4 records but not more than 20) and allow the user to input as many records of students as specified by the user except for the final rating and remarks. The values for the final rating and remarks should be based on the formula or conditions given below
final_rating = 40%mt_grade +50%ft_grade
remarks
EXCELLENT if the final_rating >=95%
VERY GOOD if the final_rating is between 85% and 94%
GOOD if final_rating is between 75% and 84%
NEEDS IMPROVEMENT if final_rating is below 75%
Display all the records with the computed final rating and remarks in a tabular format

Implement a class Sequence to store a sequence of non-negative integer values, and the length of the sequence. The class has the following private data members:
1. int length
2. int *pseq
The class shall provide the following public methods:
1. Sequence() – default constructor
2. Sequence(int lengthVal, int n1=0,int n2=0,int n3=0, int n4=0, int n5=0, int n6=0, int n7=0, int n8=0, int n9=0, int n10=0) – parameterized constructor should initialize the
length and array to sequence values passed in the arguments.
3. Sequence(Sequence &s)
4. int getLength()
5. int* getSeq()
6. void Sort(int n)
7. int RemoveDuplicates()
Return n after placing the final result in the first k elements of the array.
8. void Rotate(int steps) – a method that rotates the sequence elements clockwise for the
given steps
9. ~Sequence()
Azeem Telco Sdn. Bhd charges file, contains records for each call made by its subscribers during a month. Each record on a file contains the subscriber’s name and phone number, the phone number called, the distance from Shah Alam of the number called (in kilometers) and duration of the call-in seconds.
As a junior programmer, you are required to design and write a complete C++ program that asked the user to enter subscriber’s name and phone number, the phone number called, the distance from Shah Alam of the number called (in kilometers) and duration of the call-in seconds. The user also needs to enter types of call either Local or International call.
The cost of each call is calculated based on Table 1.
Distance from Shah Alam
Less than 25 km
25 <=km<75
75 <=km<300
300 <= km <=1000 Greater than 1000 km
Cost(RM)/minute
Local International 0.35 0.55 0.65 0.85 1.00 1.20 2.00 2.20 3.00 3.20
Your program should use the following:
1. Appropriate Control Structure
2 User Defined Function
Write a program that defines the named constant PI, const double PI = 3.14159;, which stores the value of π. The program should use PI and the functions listed in Table 6-1 to accomplish the following:
- Output the value of √π .
- Prompt the user to input the value of a double variable r, which stores the radius of a sphere. The program then outputs the following:
- The value of 4.0πr², which is the surface area of the sphere.
- The value of (4.0/3.0)πr³, which is the volume of the sphere.
A(n) ___ function doesn't return a value.
Layered
Int
Prototype
Void
Two of the main reasons for using functions are "divide and conquer" and "code reuse."
True
False
Function prototypes are placed below main(), while function definitions are placed above main()
True
False
A function prototype looks similar to the function ___, except there is a semicolon at the end.
