Update

I found Herb posted Elements of Modern C++ Style on his website.

Default is GOOD

A Default is good thing. They are good styles and inline with the following principle.

“Write for clarity and correctness first.”
“Avoid premature optimization.” By default, prefer clear over optimal.
“Avoid premature pessimization.” Prefer faster when equally clear.

Prefer range-for

If you want to go through every element in the range. Do this:

Default:

for( auto& e : c ) 
{ 
	use(e); 
}

Use smart pointers

stop using Owing pointer* new delete

use unique_ptr as default pointer, it has very low overhead.

Default:

unique_ptr<widget> factory();
void caller() 
{
	auto w = factory();
	auto g = make_unique<gadget>();
	use( *w, *g );
}

Use Non-Owing */&

If funciont only use the obejct don’t want to change the pointer, pass by raw pointer* or &.

Warning Do NOT Dereference Non-local pointer

see PDF or video for detail.

use auto

use auto for local variable when you want type to track.

## auto pb = unique_ptr{ make_unique() };
