Question

A. Please explain function studentType():

studentType::studentType()
{
numberOfCourses = 0;
sId = 0;
isTuitionPaid = false;

for (inti = 0; i < 6; i++)
coursesGrade[i] = '*';
}

B. Please explain function arrayListType() and :~arrayListType()

arrayListType::arrayListType(int size)
{
if (size <= 0)
{
cout << "The array size must be positive. Creating "
<< "an array of the size 100." << endl;

maxSize = 100;
}
else
maxSize = size;

length = 0;

list = new int[maxSize];
}

arrayListType::~arrayListType()
{
delete [] list;
}

C. Please explain function below:

arrayListType::arrayListType(const arrayListType& otherList)
{
maxSize = otherList.maxSize;
length = otherList.length;

list = new int[maxSize]; //create the array

for (int j = 0; j < length; j++) //copy otherList
list [j] = otherList.list[j];
}

Answer 1

//A
studentType::studentType()
{
numberOfCourses = 0;//setting variables
sId = 0;
isTuitionPaid = false;

for (inti = 0; i < 6; i++)
coursesGrade[i] = '*';//setting six valus of coursesGrade array to '*'
}

//B
//constructor
arrayListType::arrayListType(int size)
{
if (size <= 0)//if size is less than or equal to 0
{//then printing a message
cout << "The array size must be positive. Creating "
<< "an array of the size 100." << endl;

maxSize = 100;//and setting maxsize to 100
}
else//if greater than 0
maxSize = size;//setting max size

length = 0;

list = new int[maxSize];//creating array with size maxSize
}
//destructor
arrayListType::~arrayListType()
{
delete [] list;//free ing array memory
}

//C
//copies the list passed
arrayListType::arrayListType(const arrayListType& otherList)
{
maxSize = otherList.maxSize;
length = otherList.length;

list = new int[maxSize]; //create the array

for (int j = 0; j < length; j++) //copy otherList
list [j] = otherList.list[j];
}
