Question

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.

Answer 1

#include <iostream>

using namespace std;

int main()

{

int count;

double oil=10.88;

int FIRST_YEAR=2009,LAST_YEAR=2014;

count = FIRST_YEAR;

do

{

cout << count << ": " << oil << endl;

oil *= 1.20;

count++;

} while ( count <= LAST_YEAR );

return 0;

}

Step-by-step explanation:

• Declare the required variables.
• Use a do-while loop that runs from first year to last year .
• Display count of oil .
• Increment oil by 20% and count by 1.
