[Programming] 一個程設的題目

做一下備份

void
ReverseWord(char *begin,char *end)
{
if ((begin==NULL) || (end==NULL)) return;
if (end < begin) return;
char *q = begin;
char *p = end;
char c;
while(q < p)
{
c = *q;
*q = *p;
*p = c;
q++;
p--;
}
}

int
main()
{
char str[] = "This is a test";
ReverseWord(str, str+(strlen(str)-1));
char *p,*q;
p = q = str;
while(*p!=0)
{
if (*p==' ')
{
ReverseWord(q,p - 1);
while((*p==' ')&&(*p!=0))
p ++;
if (*p!=0)
{
q = p;
p++;
}
} else {
p++;
}
}
ReverseWord(q,p - 1);
printf("%s\n",str);
return 0;
}
