/*
rmstrong number C++ program: c++ programming code to check whether a number is armstrong or not.
A number is armstrong if the sum of cubes of individual digits of a number is equal to the number 
itself. For example 371 is an armstrong number as 33 + 73 + 13 = 371.
Some other armstrong numbers are: 0, 1, 153, 370, 407.
