Program Plan Intro

• Include required header files.
• Declare the “max()” function for two parameters.
• Declare the “max()” function for three parameters.
• Define a “max()” function with two parameters.
  • “if” statement to check “x” is greater than “y”.
    • The condition is true, return “x”.
  • Otherwise, return “y”.
• Define a “max()” function with three parameters.
  • Call “max()” function with two parameters to return the result and store it in “tmp”.
  • “if” statement to check “tmp” is greater than “z”.
    • The condition is true, return “tmp”.
  • Otherwise, return “z”.
• Define a “main()” function.
  • Declare the variables “a”, “b” and “c”.
  • Get three numbers from the user and input is assigned to the variables.
  • Call the “max()” function of two parameters and print the largest of first two numbers.
  • Call the “max()” function of three parameters and print the largest of all the numbers.
