For the questions below, assume values is an int array that is currently filled to capacity, with the following values:
 
-Which of the following loops would adequately add 1 to each element stored in values?
A) for (j=1; j<values.length; j++) values[j]++; 
B) for (j=0; j<values.length; j++) values[j]++; 
C) for (j=0; j<=values.length; j++) values[j]++; 
D) for (j=0; j<values.length-1; j++) values[j]++; 
E) for (j=1; j<values.length-1; j++) values[j]++;

B) The first array element is values[0], so the for-loop must start at 0, not 1. There are values.length elements in the array where the last element is at values.length-1, so the for loop must stop before reaching values.length. This is the case in B. In D, the for loop stops 1 before values.length since "<" is being used to test the condition instead of <=.
