John,
Very good, but you worked with an array of char's & a pointer to char's: two
strings & one a copy of the other, a sort of a crutch, he, he, he.
Came to a different solution using only the original string & the fundamentals
of the language.
char *s=" C Programming Language ";
int f1=1, f2=1;
while (*s) {
if (*s!=' ') {if (f1) printf("%c", *s); f1=0;}
else
if (!f1) {printf("%c", *s); f2=0;}
if (!f1 & !f2) f1=f2=1;
++s;
}
The backspace at the end is optional, depending on how formalist you are, if
the string has trailing blanks, but isn't necessary if it contains only blanks
or is empty; it's easy to see why: f1 won't ever be zero.
Happy coding & decoding!
Geraldo
PS: Hope to find time now for my cherished ancient Egyptian multiplication and
division [program] that I began a couple of days ago for fun & didn't bring to
an end yet for absolute lack of time.
