Message: [QUOTE="Ben Bacarisse, post: 4393209"] Yes, but it won't be any clearer. You don't use total. It will just confuse people. You can write sum += (i % 3 == 0 || i % 5 == 0) ? i : 0; Since logical expressions are either 0 or 1, you can also write sum += (i % 3 == 0 || i % 5 == 0) * i; but both are, in my opinion, inferior to a simple 'if'. What would make it clearer is to use a 'for' loop and to avoid having "global" (technically file scope) variales. Simple counted loops are best expressed using 'for'. [/QUOTE]
