Pointer question - might be silly

[billbose]

char *hname ;
char **tname ;

I know hname is a pointer to a char.
But what is tname?!

Think of pointers as variables that contain memory addresses. tname contains a memory address of a variable that contains the address of a character. Pointer to a pointer variables are often synonymous with arrays, and char ** many times indicates a pointer to an array of character strings (which are null terminated char arrays).

Dereferencing a pointer variable means you access the contents at the memory address in the pointer variable.

Clear as mud now? # Pointers are usually considered the most difficult thing to learn in C/C++.

I know I didn't really get a handle on them until I had a dream one night about programming using them. I woke up from the dream while it was still dark out and wrote down what I'd dreamed of programming by the light of the moon. In the morning I tried the code and it compiled and worked perfectly, and since then have had little trouble with them. # I'm not sure how others have gotten the concept down, though.
