 To use the **`auto`** keyword, use it instead of a type to declare a variable, and specify an initialization expression. In addition, you can modify the **`auto`** keyword by using specifiers and declarators such as **`const`**, **`volatile`**, pointer (**`*`**), reference (**`&`**), and rvalue reference (**`&&`**). The compiler evaluates the initialization expression and then uses that information to deduce the type of the variable.
 
-The initialization expression can be passed using an assignment syntax (`auto int = 0;`) or a constructor syntax (`auto int (0);`). For more information, see [Initializers](../cpp/initializers.md) and the code examples later in this document.
+The initialization expression can be passed using an assignment syntax (`auto x = 0;`), a block syntax (`auto x { 0 };`} or a constructor syntax (`auto x (0);`). It is also used to declare the loop variable in a container-based iterator loop (`for (auto x : vector)`).  For more information, see [Initializers](../cpp/initializers.md) and the code examples later in this document.
 
 The **`auto`** keyword is a placeholder for a type, but it is not itself a type. Therefore, the **`auto`** keyword cannot be used in casts or operators such as [`sizeof`](../cpp/sizeof-operator.md) and (for C++/CLI) [`typeid`](../extensions/typeid-cpp-component-extensions.md).
