minus-square@[email protected]linkfedilink18•edit-29 months agoA semicolon ends a statement, and semicolon is a statement on its own. One that does nothing. That’s why you can write int i; for (i = 0; i ᐸ 3; i++); to set i = 3. You can use that pattern to find something in an iterator, etc. But I would prefer int i = 0; while (i ᐸ 3) { i++; } for readability.
