Program Plan Intro

Sum of Numbers

Program Plan:

• • Define the “main()” function:
  • ○ Initialize the variable “number” as “0”.
  • ○ Check the value of “number”.
    • ■ If it is less than or equal to “0”, then get the input from the user and store it to the variable “number”.
  • ○ Call the function “sumNumbers()” and pass the argument “num”.
  • ○ Display the result on the output screen.
• • Define the “sumNumbers(num)” function:
  • ○ Check the value of “num”.
    • ■ If it is equal to “0”, then return “num”
    • ■ Otherwise, call the function “sumNumbers()” to recursively perform the addition operation.
• • Call the “main()” function.
