Question

Write a program that reads a
whole number of up to nine digits and prints it in words. For example, the input 13247 ought to produce "thirteen thousand two hundred forty seven".
i need a step-by-step explanation not the code and i am supposed use the switch statement

Answer 1

ya it will be mix-up of switch case and conditional statements

Answer 2

You could use integer division and mod to get each digit or convert to string and get each char as below.
digit1 = 123456789 integer divided by 100000000
digit2 = (123456789 mod 100000000) integer divided by 10000000
etc
or get string of 123456789 resulting in '123456789'
then for each char in string get digit the do the switch/case on that digit
now, you won't be working with strictly one digit at a time but this may give you an idea of how to go about it
