Chapter 11.3, Problem 22STE

Program Plan Intro

• Declare an “double” constant function named “getTemperature()” in the class “TemperatureList”.
• Define a “getTemperature()” function to return the temperature position on the list.
  • “if” statement to check the “position” is greater than or equal to “size” or “position” is lesser than “0”.
    • The condition is true, print the error message.
  • Otherwise, return the temperature position on the list.
  • The function having the keyword “const”.
  • The keyword “const” will tell the compiler that this member function should not change the value of its calling object.
