2. How is search done in #include and #include ”somelibrary.h” normally or conventionally?

1. 1. For both, search for somelibrary is done in implementation-defined manner

   
   
   

   2. When former is used, search is done in implementation defined manner and latter is used to search current directory

   
   
   

   3. When former is used, predefined directory is searched and when latter is used, current directory is searched and then predefined directories are searched

   
   
   

   4. When former is used, current directory is searched and when latter is used, standard directory is searched

   
   
   

   5. NA
