Question

Function Name: sepDigits
Inputs:
1. (double) A three-digit integer
Outputs:
1. (double) The hundreds-place digit of the input
2. (double) The tens-place digit of the input
3. (double) The ones-place digit of the input
Function Description:
This function will take in a three-digit integer (integer between 100 and 999 , inclusive)
and should return each digit as a separate number. For example, if the input is 472 , the first
output would be 4 , the second would be 7 and the third would be 2 .
Notes:
● You only have to deal with three-digit positive integers.
● The mod() and floor() functions will do all the heavy lifting.

Answer 1

CODE:

//it is a c program to seperate the digits of a 3 digit number
#include<stdio.h>
void sepDigits(int n);
main(){
   int n;
   printf("\nEnter a 3 digit positive integer:");
   scanf("%d",&n);
   if(n<100||n>999){
       printf("\nInvalid input... please entere 3 digit positive integer");
   }
   else
       sepDigits(n);
   return 0;
}
void sepDigits(int n){
   int r,i=0;
   while(n!=0){
       i++;
       if(i==1){
           r=n/100;
           n=n%100;
           printf("\n%d",r);
       }
       else if(i==2){
           r=n/10;
           n=n%10;
           printf("\n%d",r);
       }
       else if(i==3){
           r=n;
           n=n%1;
           printf("\n%d",r);
       }
   }
}
