Write a C++ program to find Strong Numbers within a range of numbers Using destructor in C++.
The destructor ~T4Tutorials_destructor() is a member function of the class T4Tutorials_destructor. Destructor ~T4Tutorials_destructor() has the same name as the name of its class T4Tutorials_destructor. The tild sign ∼ is used before the name of the destructor ~T4Tutorials_destructor().
When the object a of the class T4Tutorials_destructordestroyed, then the destructor ~T4Tutorials_destructor() also destroyed automatically.
One class T4Tutorials_Sum can have only one destructor ~T4Tutorials_destructor(). However, one class can have many constructors.
Destructor ~T4Tutorials_destructor() overloading is impossible.
~T4Tutorials_destructor() can’t have any arguments(parameters).The destructor
~T4Tutorials_destructor() has no data type.

Output
Please input the starting range of number :
1
Please input the starting range of number :
30
The Strong numbers are: 1 2. The destructor run.
