Implement a recursive method named power that takes 2 integer parameters named base and expo. The method will return the base ra
nika2105 [10]

Answer:

def power(base, expo):

   if expo == 0:

       return 1

   else:

       return base * power(base, expo-1)

Explanation:

*The code is in Python.

Create a method called power that takes base and expo as parameters

Check if the expo is equal to 0. If it is return 1 (This is our base case for the method, where it stops. This way our method will call itself "expo" times). If expo is not 0, return base * power(base, expo-1). (Call the method itself, decrease the expo by 1 in each call and multiply the base)

True/False: If a function is legally prototyped to return an integer value, it can return a structure member that is an integer
sdas [7]
#1) If a function is legally prototyped to return an integer value, it can return a structure member that is an integer data type.
Answer: True. Any method that is not declared void must contain a return statement with a corresponding return value. The data type of the return value must match the method's declared return type; you can't return an integer value from a method declared to return a boolean.
