We can provided limited help on school assignments.  We can answer questions, like you might ask your teacher and we can review your work and provides suggetions  and criticism.

But I think I can say this much.  You will have a recursive procedure that parses the expression.  When it comes to the left operand.  It places it on the stack.  When it comes to the operator, it stores it temporarily in a local variable and calls itself to to process the rest of the expression.  When it returns it places the operator on the stack and then returns to the caller.

Give it a try.
cin.getline(char *yourbuf, int max_length_allowed, char line_terminator_to_look_for);

If you use the latest STL, then it's simply cin.getline(string your_string, char terminator);
