How can I make a c++ program where the user has 2 options in a menu :1. Add a coefficient and degree of variable x to a polynomial(if the polynomial is empty, the user would be adding the first coefficient and the degree of x would be 0) 2.count the number of coefficients currently in the polynomial. While using the program, if the user decides to choose option 1 again, the value entered will be added to the existing polynomial.
