+# What the fuck is this
+
+This is your lame attempt to understand how those Network Virtual Functions sofware works as well to sharpen your understanding on C++ and C programming language. 
+
+
+## Hints
+- Compile using `g++` 
+
+## Goal 
+- Understand the difference between c++ and C
+- Understand how strcuct works and the difference between it on c++ and C
+- Understand 
+
+## Issues
+- Modification to target file only detected after 2 or more interrupt
