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%.
