Question
If a five Digit number is input through the keyboard , Write a programe to calculate the sum of its Digits?
Note:-Please when you write the code the explain it also, then only it will help me.And one more thing , I m using Turbo c++ Lite so please explain in easy terms.
Thanks in Advance !
This is an assignment or not?
You shouldn't be using Turbo C(++) either. Get a better IDE, if you can,

This sounds a lot like you intend to steal the code, pretend it's yours, and turn it in for a grade.
Ok, since I'm so kind, here you go:
:devil:Code:#include <stdio.h>
int main()
{
// Declare the variables.
int l1,ll,lox;
char buf[10];
// Initalize variables.
lox = 1;
ll = lox;
printf("Enter a number:");
fflush(stdout);
scanf("%d", &l1); // Read the number.
ll--;
while(lox < l1) lox = ((lox << 2) + (lox)) << 1; // Figure out the multiplier.
while(lox) { ll += l1 % 10; l1 /= 10; lox /= 10; }; // Sum it up.
sprintf(buf, "%%d"); // Make a format string.
printf(buf, ll); // Display the result.
return 0;
}

Do your own damn homework!
This no assignment or anything... I m just going through a book called as " Let us C" by Yashwant kanetkar. I got this problem there and i was not able to do it so i asked you.I m attaching a screen shot for that.
And also I have MS Visual C++ and Boroland C++5.02 but i do not know how to use those compiler.....
Pleae check the attached Image.
>" Let us C" by Yashwant kanetkar
Every time I see that book mentioned, bad code is involved. Would it be too forward of me to suggest that your book might suck?
>I got this problem there and i was not able to do it
Well, book exercises tend to give you everything you need in the chapter that the exercise shows up. So if I were you, I'd start by re-reading the chapter. It probably talks about division, remainder, and general numeric processing.

Whiles my code may not be the easiest to read, it actually shows using the % operator perfectly fine.

Here's a huge hint. For a number in base b, (number % base) will give you the least significant digit and (number / b) will remove the least significant digit.
I can understand that your code is just like the falling codes of matrix movie ...... you are one of expert of this forum.I m beginner.Please Help accordingly.lol ...sometimes i feel shame that what i m doing in b/w these masters ......Quote:

I feel this helps me alot....let me think and do it my self. and i m not able to do it then i will be back again to ask you all guys.Quote:

When I said it was a big hint, I basically meant that's all you need. That's the solution, and you only need to put it into code.
Damn, flashbacks to Turbo Pascal from that screenshot! :eek:
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 % 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.

printf ("%d",sum);}}
Me too, I saw that and thought "Man that's familiar, I remember that IDE," and shivered in disgust.Quote:
