 # Usage Guide
 
 **mcpp-standard** is a hands-on tutorial project focused on Modern C++ core language features. Based on the [xlings(d2x) tool](https://xlings.d2learn.org), it implements a **compiler-driven development model** for code practice that can automatically detect exercise code status and navigate to the next exercise.

 # Type Deduction - auto and decltype
 
 auto and decltype are powerful **type deduction** tools introduced in C++11. They not only make code more concise but also enhance the expressive power of templates and generics.

 # List Initialization
 
 List initialization is an initialization style that uses `{ arg1, arg2, ... }` lists (curly braces) to initialize objects, and can be used in almost all object initialization scenarios, hence it's often called **uniform initialization**. Additionally, it adds type checking for list members to prevent narrowing issues.

 # Delegating Constructors
 
 Delegating constructors are syntactic sugar introduced in C++11. Through simple syntax, they can avoid writing excessive repetitive code and achieve constructor logic reuse without affecting performance.

 Inherited constructors are a syntactic feature introduced in C++11 that solves the tedious problem of derived classes repeatedly defining base class constructors in class inheritance structures.

 `nullptr` is a **pointer literal** introduced in C++11, used to represent null pointers. It addresses the shortcomings of traditional null pointer representations (such as `NULL` and `0`) in terms of type safety and overload resolution.
