Is there a way to separate whole int to a single digit???

for example i got int of 15569542 and i wan to separate them to single digit like
1
5
5
6
9
5
4
2
please help and thank for ur help

1) Compute int%10 (modulo 10). Store the result (last digit) in some array.
2) Divide int by 10.
3) Repeat

int asd=98765, k[5], i;
for(i=0;i<5;i++)
{
k[i]=asd%10;
asd=asd/10;
}
like this correct??

Well yes, but that assumes that you know how many digits there are in advance. A more general way would be:

Code:

---


int asd = 98321, k[5], i =0;
while(asd > 0){
  k[i++] = asd % 10;
  asd = asd/10;
}

/* To print the asd digits in the right order you must print k[] in reverse */
int j;
for(j = i-1;j >= 0;j--){
 printf("%d",k[j]);
}

I haven't tested this but it's something along these lines.

i think i got it. thank for ur help =D

You're welcome.

Here's an alternate way ....

Code:

---

#include <stdio.h>

#define MAX            999999
#define str(x)          # x
#define xstr(x)        str(x)

int main(void)
{
  int d;
  char array[sizeof xstr(MAX)];

  fputs("Enter an integer from 0 to " xstr(MAX) ": ", stdout);
  fflush(stdout);
  if (fscanf(stdin, "%d", &d) == 1 && d >= 0 && MAX >= d) {
    sprintf(array, "%d", d);
    for (d = 0; array[d] != '\0'; ++d) {
      printf("%c\n", array[d]);
    }
  } else {
    puts("Try again.");
  }
  return 0;

}
