 Writing file can be done using `ofstring`, like `ifstring`, this data type provides the same functions - `open` and `close`. If a file already exists with that name, its over written, this can be changed using `ios::app` option that appends any string given to it.

+_A data structure is a group of data elements grouped together under one name._ A structure can have multiple data types grouped together to form a way of representation.

+It has a group of data types that can be called by name. It can be represented as:
+
+```cpp
+struct STRUCT_NAME {
+    DATA_TYPE NAME;
+};
+```
+
+You can access them as:
+
+```cpp
+STRUCT_NAME some_name;
+some_name.NAME
+```
