It is easy to get sum of series 2 + 4 + 6 + 8 + . . . + n in C program. In this tutorial, I’ll show you how to do it in easy way in C program. Here is a simple code for it:
printf("Enter the value of n of the series: ");
printf("Sum of the series: ");
for (i =2; i <= n; i=i+2)
printf("%d = %d ",i,s);
printf("%d + ",i);
Enter the value of n of the series: 10
Sum of the series: 2 + 4 + 6 + 8 + 10 = 30
In above code, I have tried to show number, plus sign, result and in a word equation by iterating from 2 to n using for loop by incrementing 2 and as well as summing up the series in the iteration.
