Need Help on C++ programming:

WRITE ALL THE CODE in ONE FILE

Convert Program 1 to a template.

Test with and and

Use the test found above for program 1

This is programing 1:

#include

using namespace std;

class MyArrayClass

{

//Add an 'arraySize' variable, initialize to zero ( default constructor function )

int arraySize;

//Create int * ptrArray ( default constructor set to NULL )

int *ptrArray;

public:

//Add a default constructor ( see above for what is should do )

MyArrayClass()

{

arraySize = 0;

ptrArray = NULL;

}

// Add a parm constructor that can set the array size,

// and then assigns new int[arraySize] to ptrArray. Validate size > 0.

MyArrayClass(int size)

{

if(size > 0)

{

arraySize = size;

ptrArray = new int[arraySize];

}

}

// Add a setSize function that lets the user input a size, arraySize, of an array of integers,

// and then assigns new int[arraySize] to ptrArray ( only if it is NULL ). Validate size > 0.

void setSize()

{

int size;

cout<<"Enter the size of the array: ";

cin>>size;

while(size <= 0)

{

cout<<"Size should be greater than zero."<

cout<<"Enter the size of the array: ";

cin>>size;

}

if(ptrArray == NULL)

{

arraySize = size;

ptrArray = new int[arraySize];

}

}

// Add a function, setAllValues, Have the user prompted and then enter the values for the

// array. Validate that ptrArray != NULL, if so then add values . Use pointer arithmetic

// to specify the index of the array while the user is entering the values into the array.

void setAllValues()

{

if(ptrArray != NULL)

{

cout << "Enter " << arraySize << " values to read into the array: ";

for(int i = 0; i < arraySize; i++)

cin >> *(ptrArray + i);

}

}

// Add a printAll function that prints out the array...values using pointer arithmetic.

// Validate that ptrArray != NULL, if so then print out all values

void printAll()

{

if(ptrArray != NULL)

{

for(int i = 0; i < arraySize; i++)

cout << *(ptrArray + i) << "\t";

cout << endl;

}

}

};

int main()

{

// Step 2 - Declare and Step 3 use it

// Test default constructor

MyArrayClass Array1;

Array1.setSize();

Array1.setAllValues(); // Code a Loop that asks for input for each value one at a time

// Input 10,10,20,25,30,35,42

Array1.printAll();

// Test parm constructor

MyArrayClass Array2(7);

Array2.setAllValues();

Array2.printAll();

// Test with default constructor

MyArrayClass * ptrArray1 = new MyArrayClass();

ptrArray1->setSize(); // add code to call setSize function, use 7

ptrArray1->setAllValues(); // add code to call setAllValues function: input 100,150,200,250,300,350,420

ptrArray1->printAll(); // add code to call printAll function

}
