I am trying to work on this assignment I have and I am pretty lost and do not know what to do. Any help would be greatly appreciated.
This is the assignment:
Add two methods (functions) to ex34.
/*
General Info: Write a copy constructor. Use the copy constructor in ex35 as a guide which is :
MyString(); //default constructor
MyString(char*); //conversion constructor
MyString(MyString*); //copy constructor`
Useage: Array myArray(&arrayIn);
pre: arrayIn is a pointer to an existing object of type Array
post: a new object of type Array is created. Its size and contents are identical to those of the argument
/
Array (Array)
/*
General Info: Write a method the returns a pointer to a sorted copy of invoking object. Use insertion sort as demonstrated in class. It will be easiest to write a stand-alone program to sort
a character array first. Then we'll worry about how to get it to work in class Array.
Useage: Array* sortedCopy = myArray.sort()
pre: ADT exists.
post: returns a pointer to an object of type Array containing the same elements as the invoking object but in order from smallest to largest
/
Array sort()
Name your work as asgn5.h and asgn5.cpp
Here is the ex34 that is being referenced above:
//class example
#include "ex34.h"
#include <iostream>
using namespace std;
Array::Array(int sizeIn)
{
//cout << "Array constructor" << endl;
size = sizeIn;
array = new char[size];
}
Array::~Array()
{
//cout << "Array destructor" << endl;
delete array;
}
char Array::findLargest()
{
char largest = get(0);
for (int i = 1; i < size; i++)
{
char item = get(i);
if (item != '*')
if (item > largest)
largest = item;
}
return largest;
}
void Array::insert(int pos, char elt)
{
array[pos] = elt;
}
void Array::remove(int pos)
{
array[pos] = '*';
}
int Array::get(int pos)
{
return array[pos];
}
void Array::display()
{
for (int i = 0; i < size; i++)
cout.put(array[i]);
cout << endl;
}
and the header file:
//A more complex example
#ifndef ARRAY_H
#define ARRAY_H
class Array
{
public:
/*
pre: size is a positive integer
post: Array of requested size is created with '*' in each slot
*/
Array(int size);
~Array();
/*
pre: ADT exits; 0 <= pos < size; elt is an ascii character; elt != '*'
post: elt is inserted at position pos
*/
void insert(int pos, char elt);
/*
pre: ADT exists; 0 <= pos < size
post: inserts '*' into slot pos
*/
void remove(int pos);
/*
pre: ADT exists; 0 <= pos < size
post: returns item in position pos
*/
int get(int pos);
/*
pre: ADT exists
post: displays all elements in the array
*/
void display();
/*
pre: ADT exists
post: returns value of largest item. uses function, get
*/
char findLargest();
private:
int size;
char* array;
};
#endif
Thanks guys.
