reverse the digits ????

[sunoct]

#include <stdio.h>
int main()
{
int remain = 0, reverse = 0;
int num;

printf("Enter a positive integer: ");
scanf("%d", &num);


while(num != 0)
{
remain = num % 10;
reverse = reverse * 10 + remain;
num /= 10;

}

printf("The integer with reverse digits is %d\n", reverse);


return 0;

}


if there is a "0" in the digits, like 12350
the program will skip it when reversing the integer :5321

how to make the "0" appear?????

{ 
int num,i,len; 

printf("Enter a positive integer: "); 
scanf("%d", &num); 
printf("The integer with reverse digits is "); 
len=log10(num)+1;
for(i=0;i<len;i++)
{ 
	printf("%d",num % 10);
	num/=10;
} 

return 0; 
}

  if( num%10 )
 
   printf("%d",num % 10);
    num/=10;

printf("%d",num % 10);
num/=10;
