Hi guys! So after a while of programming, I realised that my code is becomming more messy and with slower compilation time. So I ask you, what things do you commonly optimize, tricks n. stuff. (Speed Wise and Compilation Time Wise) What I know so far: You should love constants Use class prototyping a lot Please share! Thank You -MIGI0027

- pass objects as const reference when their size is 'relatively' big

Can anyone explain this?

It was a 'why', not a 'how'.

Did you seriously not find the answer even when given a relevant Google search?

Pass by const-reference has the same semantics as pass-by-const-value, but the object isn't actually copied/cloned. As a rule of thumb, large objects are likely expensive to copy, so if you don't need to make copies, you should avoid it.
