+
+The headers that define `basic_string` also define the following [user-defined literals](../cpp/user-defined-literals-cpp.md) which create a string of the specified type from the input parameters.

+| Declaration | Description |
+|--|--|
+| `inline string operator"" s(const char* str, size_t len)` | Returns: `string(str, len)` |

 ## Remarks
 
 If a function is asked to generate a sequence longer than [`max_size`](#max_size) elements, the function reports a length error by throwing an object of type [`length_error`](../standard-library/length-error-class.md).
