Assume that you have an array of integers named arr. The following program segment is intended to sum arr [0]through arr[n−1], w

Paladinen [302]

Answer:

There is only one modification in the above loop i.e. while loop should be like this--

while (i != n)

{

sum+=arr[i]; // Line 1, In question segment it is line 2.

i++; // Line 2, In question segment it is line 1.

}

Output:

Now if the array input is 1,2,3,4,5 then the output is 15.

Explanation:

In the above question, all the line of the segment is right except the body of the loop because--

The First line of the loop is increment statement which increments the value of "i" variable from 1 and the value of "i" variable will be 1 in the first iteration of the loop

The second line starts to add the value from 1'st index position of the array. Hence the segment gives the wrong answer. It adds the arr[1] to arr[n-1].

So I interchanged both lines of the while loop as shown in the answer part. I make the line 1 (In question segment) as line 2(In answer part) and line 2 (In question segment) as line 1 (In answer part).

Now It gives the correct output because it can add arr[0] to arr[n-1].
