Q1. Write a program to find sum of digits of a given input number using user defined

 Function [15 Marks]

# include<stdio.h> 

  

/* Function to get sum of digits */

int getSum(int n) 

{  

   int sum = 0; 

   while (n != 0) 

   { 

       sum = sum + n % 10; 

       n = n/10; 

   } 

   return sum; 

} 

int main() 

{ 

  int n ; 

  printf("\n enter no=");

  scanf("%d",&n); 

  printf(" %d ", getSum(n)); 

  return 0; 

} 

Q2. Write a program to accept a number and count number of even, odd and zero digits

 within that number. [25 Marks]

#include <stdio.h>
int main()
{    
      int nodd,neven,num,digit,zero=0 ;
      printf("Enter four digit number: ");
      scanf("%d",&num);
      while (num> 0)
      {
            digit = num % 10; /* separate LS digit from number */
            num /= 10;
            if(digit != 0 && digit % 2 == 0)
            {
                  neven++;
            }
            else if(digit==0)
            {
                  zero++;
            }
            else
            {
                  nodd++;
            }
      }
      printf("\nOdd digit : %d \nEven digit : %d\nZeros : %d", nodd, neven,zero);
      return 0;              
}
