Question text
This question is based on question 1 in the written Assignment 4.
The program in question 1 of the written assignment, contains an incomplete recursive
function raised_to_power(). This function returns the value of the first parameter number of
type float raised to the value of the second parameter power of type int for all values
of power greater than or equal to 0.
The correct function header for the function raised_to_power() is
Select one:
float raised_to_power(float number, int power)
int raised_to_power(float number, int power)
,float raised_to_power(int number, float power)
float raised_to_power(float number, float power)
Feedback
Your answer is correct.
The correct answer is: float raised_to_power(float number, int power)

Question text
This question is based on question 1(b) in the written Assignment 4.
The program in question 1 of the written assignment, contains an incomplete recursive
function raised_to_power(). This function returns the value of the first
parameter number of type float raised to the value of the second parameter power of
type int for all values of power greater than or equal to 0.
Based on the fact that any value raised to the power of 0 is 1, the base case for this function is
Select one:
else if (power == 0)
return (1.0);
else if (power == 1)
return (1.0);
else if (power > 0)
return (1.0);
else if (power == 0)
return (number * raised_to_power(number, power - 1));
Feedback
Your answer is correct.
The correct answer is: else if (power == 0)
return (1.0);
