+==== Void ====
+ * In a function declaration means that the function returns no value
+ * When used in a pointer declaration (called ''pointer to void''), void defines a generic pointer, so it returns an address, it is commonly used when a function is called with differents types of data, and also very used on these ways:

 ==== Prototype of Functions ====
-When there's no arguments for the function, just use the void value
+When there's no arguments for the function, just put a ''void'' itself inside the (), so for the content of arguments. 
 
 When there's arguments, you should add too a name of variable after it, the mean of this is just to be more easy to understand when reading the headers file for example
