void main()
{
int num, temp;
for(;;) {
printf("Enter number:");
scanf("%d",&num);
if(num == 0) break;
while(num) {
temp = num%10;
num = num/10;
printf("%d", temp);
}
printf("\n");
}
getche();
}
So any number will be reversed here. 12345 is five digit
number. Using while we can generalize the number of digits.
The continuous loop is ended when 0 is entered.
