Thread: Switch Statement (For Beginner)

Sorry, beginning programmer. Assignment: Take an integer keyed in from the terminal and extract and display each digit of the integer in English. Ex. 932 --> nine three two

Code:

 /*This program takes an integer keyed in from the terminal and extracts and displays each digit of the integer in English.*/


#include<stdio.h>
int main(void)
{
        //DECLARE VARIABLES
        int num;


        //ASK USER FOR INPUT; STORE
        printf("Please enter an integer: ");
        scanf("%d", &num);


        //SWITCH STATMENT
        switch (num)
        {


                case 0:
                        printf("zero\n");
                        break;
                case 1:
                        printf("one\n");
                        break;
                case 2:
                        printf("two\n");
                        break;
                case 3:
                        printf("three\n");
                        break;
                case 4:
                        printf("four\n");
                        break;
                case 5:
                        printf("five\n");
                        break;
                case 6:
                        printf("six\n");
                        break;
                case 7:
                        printf("seven\n");
                        break;
                case 8:
                        printf("eight\n");
                        break;
                case 9:
                        printf("nine\n");
                        break;
                default:
                        printf("none");
                        break;
        }

        return 0;
}

I don't know how the program works if the integer is more than one digit. Any hints would be greatly appreciated!
