C语言指针的经典解法！！
#include <stdio.h>
#include <string.h>
void sort(char* star, char* end)
{
while (star < end)
{
char p = *star;
*star = *end;
*end = p;
star++;
end--;
}
}
int main()
{
char a[100];
char b[100];
int i;
gets(a);
int len = strlen(a);
char* star = a;
sort(a, a + len - 1);
for (i = 0; i <= len; i++)
{
if (*(a + i) == ' ' || *(a + i) == '\0')
{
sort(star, a + i - 1);
star = (a + i + 1);
}
}
printf("%s", a);
return 0;
}
