Chapter 5: Problem 19

A program that calculates the total of a series of numbers typically has what two elements?

Short Answer

Expert verified

Answer: The two main elements are 1) an input mechanism to read the series of numbers, and 2) a loop/accumulator structure to calculate the total.

Step by step solution

Element 1: Input mechanism to read series of numbers

The first element is an input mechanism that allows the program to read a series of numbers provided by the user or from a file. This element is essential because it enables the program to collect the numbers that will be added up to get the total.

Element 2: A loop/accumulator structure to calculate the total

The second element is a loop/accumulator structure in which the program, using an iterator (such as a for loop), goes through each number in the series and adds it to an accumulator variable. The accumulator variable is initially set to zero and gets updated at each iteration by adding each number in the series. When the loop is complete, the accumulator contains the total of the series.
