Part A: Program 1 - WRITE ALL THE CODE in ONE FILE... MyArrayPtrArith1.cpp

Step 1 - Define the class

Write a class, myArrayClass, that creates an integer array.

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

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

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

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

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

* 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.

* 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.

* Add a printAll function that prints out the array...values using pointer arithmetic. Validate that ptrArray != NULL, if so then print out all values

testing: - code for int main() --

// Step 2 - Declare and Step 3 use it

// Test default constructor

myArrayClass Array1;

Array1.setSize(6);

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(7) Array2;

Array2.setAllValues();

Array2.printAll();

// Test with default constructor

myArrayClass * ptrArray1 = new myArrayClass;

....... // add code to call setSize function, use 7

....... // add code to call setAllValues function: input 100,150,200,250,300,350,420

....... // add code to call printAll function

Part B: Program 2 - WRITE ALL THE CODE in ONE FILE... MyArrayPtrArithTemp2.cpp

Convert Program 1 to a template.

Test with and and

Use the test found above for program 1

Part C: Program 3 - Split the code from program 2 into two files:

MyArrayPtrArithMain.cpp // contains int main() function and its code

MyArrayPtrArithTemp.cpp // contains class template code

and run.
