Write a C+ program to find Strong Numbers within a range of numbers by using the inline function in C++.
The inline function inline T4Tutorials_Strong_Numbers::function() helps to increase the execution time of a program. The programmer can make a request to the compiler to make the inline function as inline T4Tutorials_Strong_Numbers::function(). Making inline means that compiler can replace the function definitions of inline T4Tutorials_Strong_Numbers::function() to the place where this function is called a.function();.
The compiler replaces the definition of inline functions at compile time instead of referring function definition at runtime.

Output
Please Input starting range of number :
1
Please Input ending range of number :
999
The Strong numbers are:
1 2 145
