+## Dictionary 
+
+This is simple and generic dictionary. You can instantiate multiple dictionaries with
+the constructor. See interface below.
+
+Each dictionary has space for 1000 elements. 
+
+You need add the files **dic.c** and **dic.h** in your project directory.
+After that you include dic.h
+
+### Overview about functions
+
+``` c
+Dictionary * create_dict(void);
+```
+create_dict: is a simple constructor for creating 
+             a dictionary and setting up the 
+             member field 'number_of_elements'
+             and prepares the inner array 'elements'
+
+``` c
+int add_item_label(Dictionary *,char label[],void *);
+```
+add_item_label: adds item (void*) to the dictionary at given label 
+                returns 0 if adding was sucessful otherwise -1
+
+
+``` c
+int add_item_index(Dictionary *, int index, void *);
+```
+ add_item_index: adds item (void*) to the dictionary at given index (int) 
+                returns 0 if adding was sucessful otherwise -1
+
+``` c
+void * get_element_label(Dictionary *, char []);
+```
+get_element: returns the element at given label 
+
+
+``` c
+void * get_element_index(Dictionary *, int);
+```
+get_element: returns the element at given index 
+
+
+``` c
+void destroy(Dictionary *);
+```
+simple destructor function for avoiding memory leaks.
