  1. Pros: better syntax and tied to the same address, so it avoids a bug by change its destination. So it's recommended to use it whenever possible. Cons: don't take it as an alternative name, because you will depend on the compiler to optimize that away. It's better to use a macro for that matter. 0:11, it's quite the opposite: since it's more robust, you navigate through safer waters. And if you spend some time improving it, it'll become ever safer. It's only when you are making a mess is when it can become even unsafer than C.
