Assignment Write a menu driven program with the following options to call a recursive function, which raise x to the power n o must work for negative n as well as positive n. (x-n- 1/x) o ask a user for the values of x and n to call a recursive function to add the firstn terms of the series 1+1/2+1/3...1 o function output sample: 1+1/2+1/3+1/4+- 2.0833 should be printed from within the recursive function; do not create a separate function to print the series to call a recursive add the first n terms of the series 1 +... 1/3 1/2 +1 o function output sample 1/4+1/3+1/2 +1 2.0833 should be printed from within the recursive function; do not create a separate function to print the series to quit Notes: . Ask a user for the values of n and>x Validate all user inputs User should be able to run the menu as many times as user wants Include your test data as comments in main
