Answer 1

First one:

Assume that two int constants,FIRST_YEAR and LAST_YEAR have already been declared and initialized with year values (like 2009, 2014), along with a double variable oil that has been initialized with the number of barrels of oil consumed in Canada in the year given by FIRST_YEAR. 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, taking into account that each year the oil consumed increases by 20%.

This is what I have so far, but it's saying the output is incorrect


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

Answer 3

do you have oil defined? What happens when you run your own code with 2009 and 2014?

Answer 4

In case that helps at all

Answer 5

it does, move oil after print

Answer 6

i mean move oil*=1.2 after cout

Answer 7

that worked... why did it need to be after the cout statement?

Answer 8

because you had already increased the percentage and then printed it. It wants you to assume you start with 300, print then increase.

Answer 9

ohh, okay, that makes sense
