Thread: One Easy" C " Question. Please Solve and Explain.

Perhaps a while loop, (straight from my own Turbo C/C++ compiler )

Code:

#include <stdio.h>

int main(void)   {

   long number;
   int sum, c;

   /* get your number up here */

   sum = 0;
   while(number > 0)   {
      sum += number &#37; 10;  /* same as sum = sum + number % 10 */
      number /= 10;              /* same as number = number / 10 */
      printf("\n  sum = %d, number = %ld ", sum, number);
   }

   printf("\n\n\t\t\t  Hit Enter When Ready ");
   while((c = getchar()) != '\n');
   c = getchar();
   
   return 0;
}

I have done it .. it was difficult to find out but i use Modulus and divide... and did it... i will post the code here.

scanf ("%d",&num);
if (num>=1000 && num <=9999)
{d1=num%10;
d2=(num%100)/10;
d3=(num%1000)/100;
d4=(num%10000)/1000;  sum=d1+d2+d3+d4;
printf ("%d",sum);}}

i've done it for 4digit num u can xtend it further easily
