Hello George

Replying to a message of George White to William Mcbrine:

 DC>>> my book on C only talks about predefined character strings, ie:
 DC>>> static char *books[30] = {"moby dick",
"annie", etc}; But not on how
 DC>>> to read data into one.

 WM>> That's an array of pointers to constant strings. You can't read into

 GW> Not so :-(. There is no "const" in there...
 GW> That is an initialised array of strings of varying length that retains
 GW> it's value between calls to the function it's declared in. You _can_
 GW> write to them, but it's a dangerous occupation since they have the
 GW> length of the string they were initialised with and so vary in
 GW> length.


Surely *books[30] is an array of thirty pointers to char.  I know my dos
compilers will allow the strings to be changed but "moby dick" is
a string literal.
