Write a program in C to display the n terms of even natural numbers and their sum.

#include <stdio.h>

int main()

{

   int n,i,j,sum;

   printf(“Enter a number: “);

   scanf(“%d”, &n);

   sum=0;

   for(i=2,j=1;j<=n;i=i+2,j++)

   {

      printf(“%d\t”,i);

      sum+=i;

   }

   printf(“\n Total is: %d\n”,sum);

   return 0;

}

Output:

Enter a numbers: 6

2              4              6              8              10           12
