Chapter 12, Problem 7PE

Program Plan Intro

Recursive Power Method

Program Plan:

• • Global variable declaration:
  • ○ Initialize the variable “minimum” as “1”.
  • ○ Initialize the variable “maximum” as “100”.
• • Define the “main()” function:
  • ○ Initialize the variable “number” as “0”.
  • ○ Initialize the variable “exp” as “0”.
  • ○ Get the input from the user and store it to the variable “number”.
  • ○ Check the value of “exp”
    • ■ If it is less than “minimum” or greater than “maximum”, then get the exponent “exp” from the user.
      • ○ Call the function “recursivePower()” and pass the two arguments “number” and “exp”.
      • ○ Display the result on the output screen.
• • Define the “recursivePower(x, y)” function:
  • ○ Check the value of “y”.
    • ■ If it is equal to “0”, then returns is “1”.
    • ■ Otherwise, call the function “recursivePower()” recursively along with the arguments “x” and the decremented value of “y”.
    • ■ Display the result on the output screen.
• • Call the “main()” function.
