+## ADT (Abstract Data Types)
+
+*Programs created using:*
+       
+    structs, enum and union 
+
+*to create personalized DATA TYPE, like :*
+
+* Month and Data
+* Chemical Elements
+* Deck of Cards
+* etc.

+## IO (Input/Output)
+
+*Programs based on Input provided from File or Console*
+
+#### NOTE : Code to take data from console and perform operations are also provided in programs
