Recursive Multiplication Program Plan: • Define the “main()” function: ○ Initializes the variable “n1” as “0” ○ Initializes the variable “n2” as “0” ○ Check the value of “n1”. ■ If it is less than or equal to “0”, then get the first number from the user and store it to the variable “n1”. ○ Check the value of “n2”. ■ If it is less than or equal to “0”, then get the second number from the user and store it to the variable “n2”. ○ Call the function “multiplyRecursive()” and pass the two arguments “n1” and “n2”. • Define the “multiplyRecursive()” function: ○ Check the value of “x” and “y” ■ If it is equal to “0”, then return “0”. ■ Otherwise, call the function “multiplyRecursive()” to recursively perform the addition operation. • Call the “main()” function.

Program Plan Intro

Recursive Multiplication

Program Plan:

• Define the “main()” function:

○ Initializes the variable “n1” as “0”

○ Initializes the variable “n2” as “0”

○ Check the value of “n1”.

■ If it is less than or equal to “0”, then get the first number from the user and store it to the variable “n1”.

○ Check the value of “n2”.

■ If it is less than or equal to “0”, then get the second number from the user and store it to the variable “n2”.

○ Call the function “multiplyRecursive()” and pass the two arguments “n1” and “n2”.

• Define the “multiplyRecursive()” function:

○ Check the value of “x” and “y”

■ If it is equal to “0”, then return “0”.

■ Otherwise, call the function “multiplyRecursive()” to recursively perform the addition operation.

• Call the “main()” function.

Recursive Multiplication Design a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Remember, multiplication can be performed as repeated addition as follows: 7×4=4+4+4+4+4+4+4(To keep the function simple, assume that x and y will always hold positive nonzero integers.)

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.
