Hi all,

Been reading the book,  ' The C Programming Language '
by Brian W. Kernighan and Dennis M. Ritchie

Chapter 5,  Section 5.10 Command Line Arguments

There is a line of code at that section -

while ( --argc > 0 && ( *++argv ) [0] == '-' )
      while ( c= *++argv [0] )
               switch (c)  {.......}

I do not understand the portion c = *++argv[0]. From what i understand, the
'result' of that incrementing and dereferencing will be c = argv[0][1],
which is wrong.

Shouldn't the line be replaced with  c = *++argv[1] ?
FYI,
argv[0] = pointer to array of char "find"
argv[1] = pointer to array of char "-nx"
argv[2] = pointer to array of char "pattern"

The online edition of the K&R are as below -
http://www.trunix.org/programlama/c/CProgrammingLanguage/chapter5.html#s5.10

I have checked the typo report for this second edition but found that this
was not mention, so i guess, it must be my wrong interpretation. Anyway, pls
enlighten.

Thanks.

Pang
