C++ PROGRAM 1) Add dialog to the program from homework 5 problem 2. The program should ask user for last and first name, and then greet the user. After that, program asks for the coefficients of a quadratic equation. After user inputs the values, program prints the inputted values on the screen and ask user to confirm that they are correct. If user replies that the values are incorrect, the program should allow user to change the values of the coefficients. Otherwise, program solves quadratic equation and displays the solutions. After this program should ask user whether she would like to solve another quadratic equation or would like to exit. The program should be tolerant to incorrect user inputs (it should not crash if user gives incorrect or unexpected input).
Tips: start the dialog development with drawing a dialog flowchart – this will be very helpful when you start programming it. You could use example codes that we discussed in the class.
2) Design and implement a test plan (explain how we can check whether the program gives correct results or not). Using designed test plan test your code, if the testing reveals bugs, please explain what incorrect behavior you found and how you fixed the code.
