Question

Write a single statement that assigns avg_sales with the average of num_sales1, num_sales2, and num_sales3. Sample output for the given program: 5.0

Answer 1

A single line statement that computes the average would be:

avg_sales = (num_sales1 + num_sales2 + num_sales3) / 3;

You have to keep in mind that this would work in programming languages like Python. The IDLE platform will automatically give the answer in a form of a Double, thus giving you the decimal place automatically.

If you are coding in Java, you will have to declare the double in the single line statement.

avg_sales=(double)(num_sales1 + num_sales2 + num_sales3) / 3.0;

This is also assuming the you have declared "avg" as a double beforehand.

Answer 2

Double avg_sales = (num_sales1 + num_sales2 + num_sales3) / 3;
