Question

@nuts @ultrilliam

Answer 1

I already finished the question, just don't understand why the solution is what it is

Answer 2

I guess my main question would be why isn't it k<=?

Answer 3

<= is less then or equal too, while < is less then

Answer 4

but it wants 97, so while k is less than 97, it would only do 96?

Answer 5

Correct, while it would go to 97 with less then or equal to

Answer 6

couple more loops if you don't mind?

Answer 7

I just read the question... wait... what?

Answer 8

it would only go to 96, yet it counts that as right


ok then

Answer 9

yep, and it counts <= as wrong

Answer 10

hold that thought, I'm going to go put some cookies in the oven

Answer 11

I know after each year, there'll be something like `oil*1.2`, but I have no idea how to do what they want for the first year to last year thing

Answer 12

`oil = oil*1.2`
`cout << something to do with the years << ": " << oil;`
something like that maybe? or am I totally off....

Answer 13

@nuts you wanna do it, I somehow got stuck doing a physics assignmnet

Answer 14

int x;
while(FIRST_YEAR <= x || x <= LAST_YEAR)
{
oil *= oil * 1.2;
cout << x << ": " << oil;
x++;
}

did this, and it's almost correct

Remarks:
⇒ When executed, your code tried to create an excessively large file. A common cause for this is an infinite loop. Carefully check the condition and the loop body of any loop that does output.

More Hints:
⇒ You almost certainly should be using: =

Answer 15

i would but i needa sleep :(

Answer 16

;-;

Answer 17

you used a or statement
```javascript
while(FIRST_YEAR <= x || x <= LAST_YEAR) {}
```
while x is greater then x or less then last year

it will always evaluate to true, you should be using and (&&)

Answer 18

@sleepyjess

Answer 19

oooohhhhh, got the 2 confused...

Answer 20

also
```
oil *= oil * 1.2;
```
here is your second issue

you're multiplying it twice
you should either be doing

```
oil *= 1.2;
```
or
```
oil = oil * 1.2;
```

Answer 21

okay, changed that to oil *= 1.2, but still getting the same error message

Answer 22

try
```
oil = oil * 1.2;
```
then?

Answer 23

no issue with the oil statement, it got mad when I tried that way lol

Answer 24

hm, that's the only issue I see *scratching head*

Answer 25

int x;
while(FIRST_YEAR <= x && x <= LAST_YEAR)
{
oil *= 1.2;
cout << x << ": " << oil << endl;
x++;
}

that's what I have currently

Answer 26

something to do with the colon maybe?

Answer 27

wait, is it saying oil isn't even output? :thinking_face:

Answer 28

yep, saying nothing is being outputed

Answer 29

I'll just email prof in the morning...

Answer 30

give me a sec

Answer 31

Yea, let's postpone those until tomorrow, *continues to figure this out*


this would be so much easier of my visual studio installation was working

Answer 32

*re-reads instructions*

Answer 33

ooooooh

Answer 34

>x isn't defined

Answer 35

(as a number)

Answer 36

huh?

Answer 37

Figured it out

Answer 38

didn't I define it with the `FIRST_YEAR <= x && x <= LAST_YEAR`?

Answer 39

Why did you define x?
```
int x;
while(FIRST_YEAR <= LAST_YEAR) {
oil *= 1.2;
cout << ": " << oil << endl;
FIRST_YEAR++;
}
```

Answer 40

if my intuition is right

Answer 41

because it wants the year on each line

Answer 42

Yes, but first year is already defined

Answer 43

ok

Answer 44

wait, it says nothing about that

Answer 45

it just says that each year it increases by 20%

Answer 46

(hence the 1.2)

Answer 47

Write some code that uses a while statement to print on a line by itself, each of the years from FIRST_YEAR to LAST_YEAR inclusive. On each line, after the year, separated by a colon and a space, print the new value amount of oil,

Answer 48

ah "after the year" in that case

Answer 49

```
int x;
while(FIRST_YEAR <= LAST_YEAR) {
oil *= 1.2;
cout << FIRST_YEAR << ": " << oil << endl;
FIRST_YEAR++;
}
```

Answer 50

wait, why am I still defining x in that

Answer 51

```cpp
while(FIRST_YEAR <= LAST_YEAR) {
oil *= 1.2;
cout << FIRST_YEAR << ": " << oil << endl;
FIRST_YEAR++;
}
```

Answer 52

Does that wokr?

Answer 53

work?*

Answer 54

got it, then I got this

Answer 55

```cpp
int x = FIRST_YEAR ;
while(x <= LAST_YEAR) {
oil *= 1.2;
cout << x << ": " << oil << endl;
x++;
}
```

Answer 56

the stdout will still be wrong tho, hm, it's at least outputting something now though

Answer 57

yep, still says stdout is wrong

Answer 58

>_<

Answer 59

hmmm

Answer 60

@nuts any idea why this is still wrong?
