Equation reader for a numerical methods program

Hi I was just wondering if someone can put me out of my misery ...
I have written a c++ program that does numerical methods however it has no element of interactivity :( What I mean is I have no clue how to get a user's equation. At the moment what the user has to do is edit the function within the program itself. Aye you guessed it I am new to C++ heh heh . The only way I can think of doing it is reading the user's input as a string and scanning through it ... BUT I have no clue on how to do that .... Hopefully one of you programming guru's can help me heh heh .... Taa
