 A sample project which creates a shared object (.so) file on linux and calls it's function from another program.
 
 -------------------
+Shared Object (.so) File :-
 
+In simple words, a '.so' file on linux is what a 'dll' on windows. 
+
+It is a library that is linked to the executable but it is not embedded in the executable like static library (.a), 
+so it will be loaded only when the executable is launched 
+and need to be present in the system where the executable is deployed.
