Data structures and C(Self)
In C language ,declaration of variables is done as follows: <var type> <name of var1> , <name of var2>; For eg: int a,b; Then why can’t we use the declaration for pointers as follows to declare 2 interger pointers: int * a,b; instead we use : int *a, *b; ? This might be a silly doubt but please help me out.

self_doubt
I am confused about indexing being densed or sparse, Read a lot of answer but can't figure out Primary Index is always sparse : since indexing is done of key attribute and records(files) are ordered so we create index only for anchor of the block(group of records) ... record and is only for some records. Please correct me If I am wrong at some point and If I am right then please comment.
