public static int calcAverage(int a, int b, int c){ return a + b + c; }

a. 3
b. This is an error
c. 1
d. 0

Answer 1

The method calcAverage() returns the sum of its three integer parameters as a single integer value, so only 1 item is returned.

Step-by-step explanation:

The method calcAverage() in the provided code snippet does indeed have a misleading name; however, it simply takes three integer parameters and returns their sum. Hence, the correct answer to the question, 'How many items are returned from calcAverage()?' is c. 1. The method returns just one item, which is the sum of its parameters a, b, and c.

The function calcAverage() takes three integer parameters: a, b, and c. It calculates the sum of these three numbers by adding them together using the '+' operator. The result is then returned as an integer value.

So, the function calcAverage() returns the sum of a, b, and c. In this case, a = 1, b = 0.0211, and c = -0.0211. Substituting these values in the formula, the result will be:

a + b + c = 1 + 0.0211 + (-0.0211) = 1
