A TAR file in your sense is indeed a TAR.GZ file, which embed two formats : TAR and GZ. Here's the process : 1. A TAR file is ceated, concatening several files together in their uncompressed form ; note that resulting TAR file is uncompressed, 2. A GZ file is created by compressing the previous TAR file. So to decompress a TAR.GZ file, you have to : 1. Decompress the compressed GZ file and 2. "Untar" (unarchive) the uncompressed resulting TAR file. Note that you can compress a TAR file with other popular compressors (bzip2 => TAR.BZ2, 7zip => TAR.7Z...).

Not always : a void pointer lives its own live and you can made point it on every type or on... nothing ! :)

My 2 cents, I prefer

char* c;

too, as I've learned years ago. To quote Wikipedia and what I've learned (Pointers section) : "A pointer is a data type that contains the address of a storage location of a variable of a particular type." Nevertheless, this same Wikipedia section points out that writing it is a matter of style :

char* c;

char * c;

or

char *c;

All right for everyone :) Not mentioning the confusing writing for arrays of pointers... So the type of "char*" is a "pointer on a char". The type of "int*" is a "pointer on an int". And so on...
