you could read the digits character by character into an array until newline is found and then print the array in the reverse order. While reading the digits you could form a sum at the same time by adding the digits.

You can take integer from user and use "div and mod" method for reversing as well as calulating sum of digits in a number.

Well have a look on this

CODE


void main()
{
    int num,sumOfDigits=0;
    printf("Enter Number : ");
    scanf("%d",&num);
    printf("Reversed Number is : ");
    while(num>0)
    {
        sumOfDigits += num%10;
        printf("%d",num%10);
        num /=10;
    }
    printf("\nSum Of Digits is : %d",sumOfDigits);
}



now validations like numbers should be within range of integer and it should be positive etc etc.... you can take care of it. smile.gif

The program is-

CODE
/*Reverse No.*/
#include<stdio.h>
# include<conio.h>
# include<iostream.h>

main()
{
    int a,n,s=0,t;
    printf("Enter the number=");
    scanf("%d", &a);
    for(n=a;n!=0;n=n/10)
    {
        t=n%10;
        s=(s*10+t);
    }
    printf("The Reverse No. is %d", s);
    getch();
}


Please try this.

The program to find the sum of the no.s-
CODE
/*Sum of the digits of a given no.*/

#include<stdio.h>
#include<conio.h>
#include<iostream.h>

main()
{
      int n;
      int s=0, r;
      printf("Enter the no...");
      scanf("%d", &n);
      while(n>0)
      {
                r=n%10;
                s=s+r;
                n=n/10;
      }
      printf("The SUM VALUE is=%d",s);
      getch();
}

/*end of main*/

Please try this.
