Lanuage C++ (Beginner level)
Please...I need help with this....
*******************************************************************************************
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
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…
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.
Solution
Answer:
Note: Multiple Questions, I solved the first program please post the other program as separate question
Program code:
//header files
#include<iostream>
using namespace std;
//declares the myArrayClass
class myArrayClass
{
//public Access specifier
public:
//declares the data members
int arraySize;
//declares pointer array
int * ptrArray;
//default constructor implementation
myArrayClass()
{
//assigns array to zero
arraySize=0;
//assigns the null pointer
ptrArray=NULL;
}
//parameterized constructor Implementation
myArrayClass(int size)
{
//checks the size is greater than 0
if(size>0)
{
//assigns the array size
arraySize=size;
//creates a pointer to array size
ptrArray=new int[arraySize];
}
}
//defines the setSize for setting the size
void setSize(int size)
{
//checks the size and the pointer array
if(size>0 && ptrArray==NULL)
{
//assigns the size is array size
arraySize=size;
//creates a pointer to array size
ptrArray=new int[arraySize];
}
}
//defines the setAllValues function
void setAllValues()
{
//getting the values from user
cout<<\"Enter all values: \";
//assigns the pointer array to null
if(ptrArray!=NULL)
{
//declares the pointer
int *ptr=ptrArray;
//loop to get the values
for(int i=0;i<arraySize;i++)
{
//getting input as pointer
cin>>(*ptr);
//increments the pointer
ptr++;
}
}
}
//defines the function printAll()
void printAll()
{
//assigns the array is NULL
if(ptrArray!=NULL)
{
//assigns a pointer array
int *ptr=ptrArray;
//loop to print the elements
for(int i=0;i<arraySize;i++)
{
//printing the values
cout<<(*ptr)<<endl;
//increments the pointer
ptr++;
}
}
//else statement
else
{
//printing the messages
cout<<\"No values to print.\"<<endl;
}
}
};
//main program for the class
int main()
{
//defines object for the class
myArrayClass Array1;
//calls the function with the created object
Array1.setSize(6);
//calls the function with the created object
Array1.setAllValues();
//calls the function with the created object
Array1.printAll();
//pauses the console
system(\"pause\");
//return statement
return 0;
}
Sample Output:
Enter all values: 100 150 200 250 300 350
100
150
200
250
300
350
