Hi Keith and welcome to bytes.com!

What have you tried so far? What is and what isn't working?

#include<stdio.h>
main()
{
int i,copy,no=0,input,a[100];//a[100] is for storing the values between commas you can also use malloc();
printf("ENTER A NUMBER : ");
scanf("%d",&input);
/*for storing the values b/w commas*/
copy=input;
for(i=0;i<100;i++)
{
no++;
a[i]=copy%1000;
copy/=1000;
if(copy<1)
 goto out;
}
out :
for(;no>0;)
printf("%i,",a[--no]);
printf("\b");//this statement is given so that the last comma is deleted
}
