Sales Tax Program Refactoring

Program Plan:

• Declare a function named “calc()”. This function accepts a parameter named “amt”. Inside the function,
  • Assign state sales tax value to the variable “s_salestax”.
  • Assign county sales tax value to the variable “c_salestax”.
  • Calculate state sales tax and store it in a variable “sstax”.
  • Calculate county sales tax and store it in a variable “cstax”.
  • Calculate total tax and store it in a variable “totaltax”.
  • Calculate total sale and store it in a variable “totalSale”.
  • Print the values.
• Inside the “main ()” function,
  • Get the amount from the user and store it in a variable “amount”.
  • Call the function “calc()” by passing “amount” as the argument.
• Call the main function.
