The following c-e are done in this function Use istringstream to create an input string stream called instream. Initialize it with each string that is read from the data file using the getline method. Read the coordinates for the center and the radius from instream to create the circles Include a try catch statement to take care of the exception that would occur if there was a file open error. Display the message “File Open Error” and exit if the exception occurs Display all the circles in this vector using the toString method Use an iterator to iterate through the vector to display these circles Display the count of all the circles in the vector using the getCount method Display the count of all the circles in the vector using the vector size method Clear the vector Create a circle called c using the default constructor Display the current count of all the circles using the getCount method on c Display the current count of all the circles using the vector size method Write functions in your main driver cpp file that perform the actions b-l.

make extensions to my code to do the following:
- Extend the driver class to do the following:
- Declare a vector of circles
- Call a function with signature inputData(vector<Circle> &, string filename) that reads data from a file called dataLab4.txt into the vector. The following c-e are done in this function
- Use istringstream to create an input string stream called instream. Initialize it with each string that is read from the data file using the getline method.
- Read the coordinates for the center and the radius from instream to create the circles
- Include a try catch statement to take care of the exception that would occur if there was a file open error. Display the message “File Open Error” and exit if the exception occurs
- Display all the circles in this vector using the toString method
- Use an iterator to iterate through the vector to display these circles
- Display the count of all the circles in the vector using the getCount method
- Display the count of all the circles in the vector using the vector size method
- Clear the vector
- Create a circle called c using the default constructor
- Display the current count of all the circles using the getCount method on c
- Display the current count of all the circles using the vector size method
- Write functions in your main driver cpp file that perform the actions b-l. Your code should be modular and your main program should consist primarily of function calls
My code:
Circle:
#include <iostream>
#include "CircleHeader.h"
#include <string.h>
#include <math.h>

//def to find Circumference

//def to return cirlce as a string
string Circle::toString()
{

s="("+to_string(getX())+","+to_string(getY())+"):"+to_string(getRadius());
return s;
}
double Circle::getDistance(Circle other)
{
return sqrt((x - other.getX())*(x - other.getX()) + (y - other.getY()) * (y - other.getY()));
}
void Circle::moveTo(int newX,int newY)
{
x += newX;
y += newY;
}
bool Circle::intersects(Circle other)
{
int radSumSq = (radius + other.getRadius()) * (radius + other.getRadius());
if (getDistance(other) >= radSumSq)
return true;
else
return false;
}
void Circle::resize(double scale)
{
radius = radius*scale;
}
Circle Circle::resize(int scale)
{
Circle c(x, y, (radius*scale));
return c;
}
CircleHeader:
#ifndef CircleHeader_H
#define CircleHeader_H

using namespace std;
//declaring class

string toString();
double getDistance(Circle other);
void moveTo(int newX,int newY);
bool intersects(Circle other);
void resize(double scale);

};
#endif
Main CPP:
#include "CircleHeader.h"
#include <iostream>
using namespace std;
int main()
{
//first circle

Circle circleTwo(0,0,4);
cout<<"Circle one is : "<<"("<<circleOne.toString()<<endl;

cout<<"Distance Between Circle one and Circle two: "<<circleOne.getDistance(circleTwo)<<endl;Circle circleThree = circleTwo.resize(10);

//showing area of all circles
