Assignment Write a menu driven program with the following options

• to call a recursive function, which raise x to the power n
  • must work for negative n as well as positive n. ( x ⁿ = 1/ x ⁿ )
  • ask a user for the values of x and n
• to call a recursive function to add the first n terms of the series 1+1/2+1/3...1/n
  • output sample: 1+1/2+1/3+1/4+= 2.0833
• to call a recursive add the first n terms of the series 1/n + 1/3 + 1/2 +1
  • output sample 1/4 + 1/3 + 1/2 +1 =2.0833
• 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.
