Hello all,

My assignment is to write a quadratic equation solver. I have written the function, and it compiles well. However that is not the issue. The requirements are that it follows a command line interface specification as follows:

<program name> -r <quadratic equation>

In other words, the user is to enter "-r" followed by the equation, and the program will then output the roots as two numbers on the next line, and that's it. That means I can't have any other expressions like "Enter the value of a..." or "Enter the value of b..." and then cin my b variable. How do I write the piece of code so that all the user has to do is type "-r" and then the equation, and this will call my function and output the results? Any suggestions or guides..?
