Assuming that was intended to be a solution to the original
problem[1]: Sorry, but you missed point.
However, it is an interesting solution to another problem,
namely that of compressing any sequence of blanks in a
string to exactly one space. Interesting insofar, as it is
very inefficient by copying the tail part of the string over
and over again. So, no cigar here either. ;o)
A more idiomatic and better performing solution to that
would be something along the lines of:
char *SpaceSquash( char *str )
{
char *s = str, *d = str;
while ( *s )
{
*d++ = *s;
if ( *s++ == ' ' )
while ( *s == ' ' )
++s;
}
*d = '\0';
return str;
}
[1] K&R2 Exercise 1-9: Write a program to copy its input
to its output, replacing each string of one ore more
blanks by a single blank.
