(Population projection) Rewrite Programming Exercise to prompt the user to enter the number of years and displays the population after the number of years. Use the hint in Programming Exercise for this program. Here is a sample run of the program:

Programming Exercise (Population projection) The U.S. Census Bureau projects population based on the following assumptions:

■ One birth every 7 seconds

■ One death every 13 seconds

■ One new immigrant every 45 seconds

Write a program that displays the population for each of the next five years. Assume the current population is 312,032,486 and one year has 365 days. Hint : In C++, if two integers perform division, the result is the quotient. The fractional part is truncated.

For example, 5 / 4 is 1 (not 1.25) and 10 / 4 is 2 (not 2.5). To get an accurate result with the fractional part, one of the values involved in the division must be a number with a decimal point. For example, 5.0 / 4 is 1.25 and 10 / 4.0 is 2.5.
