Question

Consider the following declaration: double[] sales = new double[50]; int j; Which of the following correctly initializes all the components of the array sales to 10.

(i) for (j = 0; j < 49; j++) sales[j] = 10;
(ii) for (j = 1; j <= 50; j++) sales[j] = 10;

Answer 1

The answer is "None of these".

Explanation:

In the given question an array "sales[]" is declared, which contains 50 double type elements, and in the next line, an integer variable j is defined, which uses a for loop. In this question two options is given, in which both are not correct, that can be described as follows:

• In option (i), A loop is defined that, uses variable j which starts with 0 and ends with 48, So total elements are 48 that's why it is not correct.
• In option (ii), A loop will use variable j that, starts with 1 and ends with 49, That's why it is not correct.
