Program Plan Intro
Recursive Power Function
Program Plan:
- Include the required header files.
- Declare the necessary function prototype and constants.
- Define the main() function,
- Get the required input from the user.
- Call the method “power()” to compute the power of the given elements by passing the values as the arguments.
- The function gets executed in recursive way to compute the power of the elements that is given.
- Define the “power()” function,
- A condition that validates whether the given element is greater than 0 to compute the power recursively.
- If the condition becomes true after validation, the power value that is computed will be returned after performing the calculations.
- If the condition fails, it will return the value as “1”.

Exponent
y Catherine Arellano
mplement a recursive function that returns
he exponent given the base and the result.
for example, if the base is 2 and the result is
3, then the output should be 3 because the
exponent needed for 2 to become 8 is 3 (i.e.
23 = 8)
nstructions:
1. In the code editor, you are provided
with a main() function that asks the
user for two integer inputs:
1. The first integer is the base
2. The second integer is the result
2. Furthermore, you are provided with the
getExponent() function. The details of
this function are the following:
1. Return type - int
2. Name - getExponent
3. Parameters
1. int - base
2. int - result
4. Description - this recursive function
returns the exponent
5. Your task is to add the base case and
the general case so it will work

Recursive Power FunctionWrite a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer. Demonstrate the function in a program.

- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forward*C Language The greatest common divisor of integers x and y is the largest integer that divides both x and y. Write a recursive function GCD that returns the greatest common divisor of x and y.
