When writing your C program, you can include files in two ways. The first way is to surround the file you want to include with the angled brackets < and >. This method of inclusion tells the preprocessor to look for the file in the predefined default location. This predefined default location is often an INCLUDE environment variable that denotes the path to your include files. For instance,...

The only "better" is what is more readable and maintainable and sensible to the people reading and writing the code.Any compiler worth having won't care either way, and will generally produce identical or equivalently performing code in each case.

correct ans is  pa[5].after executing the statement pa=a;pa will point to the array a.now array a has 2 pointers which are a and other is pa.we can use subscript operator for pointers also when it points to an array.so pa[5] will give 6th value in that array.
