Problem
Many reverse Polish calculators use not only a stack but also provide memory locations where operands can be stored. Extend the project to provide an array to store polynomials. Provide additional commands to store the top of the stack into an array entry and to push the polynomial in an array entry onto the stack. The array should have 100 entries, and all 100 positions should be initialized to the zero polynomial when the program begins. The functions that access the array should ask the user which entry to use.
