Suppose that sales is an array of 50 components of type double.Which of the following correctly initializes the array sales?
A) for (int 1 = 1; j <= 49; j++)
Sales[j] = 0;
B) for (int j = 1; j <= 50; j++)
Sales[j] = 0;
C) for (int j = 0; j <= 49; j++)
Sales[j] = 0.0;
D) for (int j = 0; j <= 50; j++)
Sales[j] = 0.0;

Option A and B will only initialize the first 49 elements of the array, leaving the last element with the default value of 0.0.

Option D will result in an ArrayIndexOutOfBoundsException because the loop is iterating one time more than the array size.

Option C correctly initializes all 50 elements of the array as 0.0.
