Answer:

1)The sum of all even numbers

#include <stdio.h>

int main()

{

   int a,n,sum;

   /* it is the range of naturalnumbers*/

   printf("enter the range ");

   scanf("%d",&n);

   for(a=1;a<=n;a++)

   {

       if(a%2==0)

       {

       sum=sum+a;

       }

   }

   printf("the sum of even=%d",sum);

   return 0;

}

Output:-

Enter the range 6

the sum of even 12

2)The sum of all odd numbers

#include <stdio.h>

int main()

{

   int a,n,sum;

   /* it is the range of naturalnumbers*/

   printf("enter the range ");

   scanf("%d",&n);

   for(a=1;a<=n;a++)

   {

       if(a%2!=0)

       {

       sum=sum+a;

       }

   }

   printf("the sum of odd=%d",sum);

   return 0;

}

Output:-

enter the range 6

the sum of odd 9
