Doubt in first solved example ( sum of digits of n)

#1

how can we possibly know that the number the user entered while running the program be a float . shouldn’t we after doing the arithmetic operation N=N by 10 convert the resultant n to integer and then move forward

#2

We have to define the datatype of our number before taking its input. For example, if we write int n and input the value 10.7, the value stored in n will be 10 only as the code implicitly converts it to int.
