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:
Python Code
Explanation:
total = 0.0
change = 0.0
itemone = float(input("Enter the first price: "))
itemtwo = float(input("Enter the second price: "))
itemthree = float(input("Enter the third price: "))
total = itemone + itemtwo + itemthree
print("Total:", total)
cash = float(input("Cash given: "))
change = total - cash
print("Your change:", change)
Answer: b)because near-critical paths could become critical paths with small delays in these activities
Explanation: Program evaluation and review technique(PERT) technique is used for management of the project .The organizing, maintenance,coordination of any task is done by this chart. The non-critical activities need to be observed carefully because they may create near-critical methods which can lead to complexity.
Other options are incorrect because not all activities are equally rather monitoring is done to avoid errors and slack can occur at any path . Small delays can be caused but not complete project can get delayed and there can be risk of complexity rather than being uncompleted.Thus, the correct option is option(b).
