1. % is used to get remainder of a number by dividing it by other number. And if we do modulus of number by 10 then the last digit of number is remainder. Means 123%10=3 or 12%10=2. I hope this will make you clear.

2. d is empty var, when n is suppose 123, n % 10 is takeing underoot of 123(n) by 10 and saving the remainder 3 into d for 1st loop iteration and then so on.

1. I used this program but it is not working for numbers starting with zero.
For example,
001 should give me 100; but it gives me 1

1. rev is 0 in 1st iteration so its just rev = (0 * 10) + 3;
you can cout <<rev<<" "; below rev that youll see each iteration value of rev;

this was really helpful… thanku.. but I couldn’t find the solution to write a program to enter a number and print the sum of digits.

1. #include
#include
#include
void main()
{
clrscr();
int n,x,y,sum;
cout<>n;
x=n%10;
y=n/10;
sum=x+y;
cout<<"the sum is:"<<sum<<endl;
getch();
}

3. your programs having error always
i think u have to check them and then post ur programs………………..
when i see ur program having error i fell veryyy fustrated …………
