Unlike macros, functions do not have these disadvantages. However, the biggest disadvantage of functions is low execution efficiency (increasing the overhead of function calls and the difficulty of compiler optimization).
In light of this, you can use inline functions when necessary. Similar to macros, inline functions are expanded at the call point. The difference is that inline functions are expanded during compilation.
Inline functions have the advantages of both functions and macros:
- Strict type checking is performed for inline functions.
- Parameters are evaluated only once for inline functions.

**Reason:**
Smart pointers automatically release object resources to prevent resource leakage, but they require extra resource overheads. For example, the classes, constructors, and destructors automatically generated by smart pointers consume more resources such as memory.
