I GUESS this exercise could be a typical use of stack and stack 
operations: push, pop.
First, have a stack implemented, which can handle arbitrary size, also 
implement push and pop. The rest of the task is simple:
(draft)

ch = read character;
if (ch == space){
   write each stack character using pop();
   write whitespace;
}
else{
   push(ch);
}

Make a loop of the above and that's all.
Of course, if you need to take care of new lines and tabs too, then you 
can extend the first "if" statement, like:
if (ch == space || ch == tab || ch == newline, ...)

Working implementations attached:
- reverse.c
   It can work with any word-length.
- reverse_simple.c
   This is more compact, however max word length is hard coded.

Both read from stdin and write to stdout (redirect if you need). They 
read until EOF is read. Both are simple C programs, no C++ here. The 
stack implementation is primitive, no checking performed, however there 
should be no problem of that, due to the known use of the stack.

Hope they help.
