Question

How would you declare an array variable called gross Salary to store 10 values using the double data type?

A) double[] grossSalary = new double[10];
B) double[] grossSalary = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0};
C) double[] grossSalary = double[10];
D) double[] grossSalary = [0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0];

Answer 1

To declare an array of double to store 10 values called grossSalary, the correct declaration is 'double[] grossSalary = new double[10];'.

Step-by-step explanation:

To declare an array variable called grossSalary to store 10 values using the double data type, the correct option is:

A) double[] grossSalary = new double[10];

This line of code initializes an array of doubles with 10 slots, defaulting all values to 0.0 since double types are initialized with 0.0 by default. It is a common way to allocate memory for a fixed size array where the individual elements will be assigned later.
