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].
Answer:
Following are the statement is given below
if(updateDirection ==1) // check condition
{
++numUsers; // increments the value
}
else
{
--numUsers; // decrement the value
}
Explanation:
Following are the description of statement
- Check the condition in the if block .If the "updateDirection" variable is 1 then then control moves to the if block otherwise control moves to the else block statement.
- In the if block the statement is "++numUsers" it means it increment the value by 1 .
- In the else block the statement is "--numUsers" it means it decrement the value by 1 .
It is true the reason why it is true is
