Classes Constructor and Destructor

[jshm415]

Hello, I am writing few lines of codes for my project and I am not sure how to approach this problem.

The instruction says:

Add a function call loadDocument that takes the name of the file. The function will read in the text file and create a new Line for each sentence read with Line id equal to the location in the text file. After, set the linecount.

Is Line a class or an array of the class? In previous classes, I did make an array of classes. Also, how do you mean by location in the text file. Can you please help me?

Here's what I have so:

#include <iostream>
#include <fstream>
#include <string>


using namespace std;

/* Start of Class Line */
class Line
{
public: 
	int id;
	Line();
	Line(string str1 )
	{
		int id = rand();
		*str=str1;
	}
	~Line();
	int getWordCount();
	void setString(string str1);
	void setWordCount(int value1);
	int getCharCount();
	void setCharCount(int value2);

private:
	string* str;
	int wordcount;
	int charcount;
};

Line::Line()
{
	int id = rand();
	string* str = new string;

}

Line::~Line()
{
	delete str;
}
void Line::setString(string str1)
{
	*str = str1;
}
int Line::getWordCount()
{

	return wordcount;
}

void Line::setWordCount(int value1)
{
	wordcount = value1;
}

int Line::getCharCount()
{
	return charcount;
}

void Line::setCharCount(int value2)
{
	charcount = value2;
}

/* End of Class Line */

/* Start of Class Document */

class Document
{
public:
	int id;
	int getLineCount();
	void setLineCount(int value3);
	int getwordcount();
	void setwordcount(int value4);
	~Document();
	Document()
	{
		Line* line = new Line[];
	}
private:
	int linecount;
	int wordcount;
	string name;
	Line* line;
};

Document::~Document()
{
	delete [] line;
}

int Document::getLineCount()
{
	return linecount;
}

void Document::setLineCount(int value3)
{
	linecount = value3;
}

int Document::getwordcount()
{
	return wordcount;
}

void Document::setwordcount(int value4)
{
	wordcount = value4;
}



/* End of Class Document */


int main()
{
	

	int number;

	cout << "Please enter number " << endl;
	cin >> number;

	switch(number)
	{
	case 1: 
		cout << "Load Document " << endl;
	case 2:
		cout << "Output Document " << endl;
	case 3: 
		cout << "Parse Document " << endl;
	case 4: 
		cout << "Analyze Document " << endl;
	default:
		cout << "Exit " << endl;

	}
	return 0;
}




void loadDoucment()
{
	ifstream myfile ("example.text");
		if (myfile.is_open() )
		{
			
		}
}
