[E-12]Write a main() program that
first asks the user for an integer, N, and then calculates three sums: the sum
of the even integers, the sum of the odd integers, and the sum of all integers
from 0 to N. The output of the program is:
Enter n: 7 Sum = 28, Sum of Odd = 16, Sum of Even = 12
Use the previous program as a start for this one. There are several ways to write this program. Try to write a nice, conceptually clean program.
The best way to write this program is to use the formulas that calculate each sum in one step. But, to practice programming, implement this program with a loop.
