Write a program in C++ to read a number n and find out the sum of the integers from 1 to
then from 1 to 3, then 1 to 4, and so on and to display the sum of the integers from 1 to
n.
For example, from
1 to 2 = 1
1 to 3 = 3
1 to 4 = 6
1 to 5 = 10
1 to 6 = 18

1. Provide a constructor, which takes arguments (you may set values of data members to 0).
2. Write getter and setter functions (input and show functions) for the Date class.
3. Also write a member function void CompareDates(Date d1, Date d2) which tells which date comes first.
Create a class Circle having a data member radius. The class should be capable of calculating the area. Compare the areas of two circles and also displaying the area of which circle is greater. Make all the necessary function as needed including constructors.
A flask is charged with 2.00 atm of nitrogen dioxide and 1.00 atm of dinitrogen tetroxide at 25 °C and allowed to reach equilibrium. When equilibrium is established, the partial pressure of NO2 has decreased by 1.24 atm.
(a) What are the partial pressures of NO2 and N2O4 at equilibrium?
(b) Calculate and for Kp and Kc following reaction at 25 °C.
2NO2 (g) ↔ N2O2 (g)
(Answer: K p = 2.80; K c = 68.6)
