Question

What does the following method do?

void spread (int[] values)
for (int index= 1; index < values.length; index++) values[index] = values[0].
a.It changes an array by copying the element in cell 0 to all other cells.
b.It changes an array by making every element the same as the value of its index It changes an array by making every element zero.
c.It makes a change to the formal parameter but does not make a change to the caller's array

Answer 1

The spread method copies the value of the first element (index 0) of an array into all other elements, resulting in all elements having the same value.

Step-by-step explanation:

The spread method in the code you've provided changes an array by copying the element in cell 0 to all other cells in the array. This is done by iterating over the array starting at index 1 (the second element) and setting each element to the value of the first element (index 0). Once the for loop completes, all elements in the array will have the same value as the first element.
