Can somebody please tell me how to do this is C++?

" Write a program that, by entering a series of elements of integers [ 1, 2, 25, 35, 48 ] , calculates the sum of all even numbers "

I know how to do that for 1 to n

But how to do it when I have range of numbers?

1) forget about code.  how would you do it, by hand?  Write out the steps in English.
2) break the problem down into small pieces that are independent.  For example, it doesn't matter HOW you get the list/array of numbers, but once you have it, what do you need to do with it?  Write that part.  For the time being, you could even hard-code  your array, and worry about getting user input later.

But you showed 2...n. Your solution isn't generalisable, but it would be quite easy to make it generalisable.
