m05B C++ Please extend my code to do the following: Write a brand new driver program that does the following: Creates a circle object circleOne at (0,0):5. Creates a pointer c1Ptr to circleOne Creates a circle object circleTwo at (-2,-2): 10 Creates a pointer c2Ptr to circleTwo Use greaterThan to check if circleTwo is bigger than circleOne and display results Declare an array of pointers to circles- circlePointerArray Call a function with signature inputData(circlePointerArray, string filename) that reads data from a file called dataLab4.txt into the array The following h-k 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”…

A1: File Handling with struct C++ This program is to read a given file and display the information about employees according to the type of employee. Specifically, the requirements are as follows. Read the given file of the information of employees. Store the information in an array or arrays. Display all the salaried employees first and then the hourly employees Prompt the user to enter an SSN and find the corresponding employee and display the information of that employee.
