Program for converting decimal into binary.

#include <stdio.h>

int main()

     {

     int n, i, j, binary=0,input;

  printf("Enter a number to convert : ");

     scanf("%d",&n);

     input=n;

     i=1;

      for(j=n;j>0;j=j/2)

       {

        binary=binary+(n%2)*i;

        i=i*10;

        n=n/2;

       }

     

     printf("\nThe Binary of %d is %d.\n\n",input,binary);

 }

Program for Sum of digits...

#include <stdio.h>

 int main()

{

   int n, t, sum = 0, remainder;

   printf("Enter an integer\n");

   scanf("%d", &n);

   t = n;

   while (t != 0)

   {

      remainder = t % 10;

      sum       = sum + remainder;

      t         = t / 10;

   }

   printf("Sum of digits of %d = %d\n", n, sum);

   return 0;

}

Program for Palindrome..

#include <stdio.h>

int main()

{

    int n, r_integer = 0, remainder, o_integer;

    printf("Enter an integer: ");

    scanf("%d", &n);

    o_integer = n;

    while( n!=0 )

    {

        remainder = n%10;

        r_integer = r_integer*10 + remainder;

        n /= 10;

    }

     if (o_integer == r_integer)

        printf("%d is a palindrome.", o_integer);

    else

        printf("%d is not a palindrome.", o_integer);

    

    return 0;

}

Programe for Armstrong Number.

#include <stdio.h>

int main()

{

    int number, o_integer, remainder, result = 0;

    printf("Enter a three digit integer: ");

    scanf("%d", &number);

    o_integer = number;

    while (o_integer != 0)

    {

        remainder = o_integer%10;

        result += remainder*remainder*remainder;

        o_integer /= 10;

    }

    if(result == number)

        printf("%d is an Armstrong number.",number);

    else

        printf("%d is not an Armstrong number.",number);

    return 0;

}
