Terrell, a programmer, is creating a website for an online merchant and wants the program to calculate the total price based on the quantity of items ordered and the tax on the total. in order to avoid specifying the procedure in every new situation, he can create and use a a) code. b) function. c) global variable. d) subroutine.

The answer should be C because a global variable is throughout the entire site

Global variable ( C )

Explanation:

A global variable is variable that covers/visible in all aspects of the computer program. a group of global variable is called a global environment.

global variables are variables declared outside a function which makes it visible in all aspects of the program written,like in (the function of calculate the total price based on quantity of items purchased and the tax on the total),using a global variable which is visible will help to always do the calculations every time any change in quantity of items ordered is made. a similar variable to this is the local variable but it is declared inside a function and it has to be declared each time because it is not visible throughout the program.
