wap to print and add/sum of all even numbers by using for loop.

 

#include<stdio.h>

#include<conio.h>

 main()

{

      int even=2,i,sum=0,n;

  

   printf("how many even no. u want to sum ");

   scanf("%d",&n);

   printf("all the even no. to %d is ",n);

   for (i=1;i<=n;i++)

   {

     if(i%2 == 0)

      { 

         printf("\n %d",i);

      }

         sum=sum+even;

         even=even+2;

   }

   

   printf("\n sum of even numbers is %d ",even);

}

output:

how many even no. u want to sum 9 all the even no. to 9 is 2 4 6 8 sum of even numbers is 20
