Program Plan Intro

Sum of Numbers

Program Plan:

• Define the “main()” function:
  • Initializes the variable “number” is “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.
