There are following two major issues associated with CPP programs:
When a program is terminated, the entire data is lost.
If you have to enter a large number of data, it will take a lot of time to enter them all in the different programs.
Suggest a solution and elaborate the same with the help of suitable examples.
Water is solid if its temperature is 273 Kelvin and below. It is liquid when its temperature is between 273 Kelvin and 373 Kelvin. When it is 373 Kelvin and higher, it becomes gas. Create a program that will ask for the temperature of the water in Kelvin, and display the its phase. Use Boolean operators and If statements.
A certain organization needs to elect its new president. So, they started looking for potential candidates. A candidate must be 30 to 40 years old and must be male in pursuance to its by-laws.

Write a program to overload binary – (minus) operator for Number class using friend function. Number class have
two data members as num1 and num2.
Write a program that demonstrate the use of constructor with default
arguments for the following problem. Define a class Person with data member as name
and age. Create three objects with no argument, one argument name and two argument
name and age. You are not allowed to create more than one constructor.
Create a class Number with a pointer as a data data member of integer type. Write user defined copy constructor to
the class and implement the deep copy for the Number class objects. So when a new object is created from an
old object of the Number class, pointer data member can point different memory block.
