将一个句子中的单词逆序,先将整个句子逆序,再将句子中的单词逆序.

＃include <iostream>
using namespace std;

void RevStr(char src[])
{
char *start=src, *end=src, *p=src,e;
int i=0;
do
{
if(*p==' '|| *p==','|| *p=='.'|| *p==';'|| *p=='!'||! *p)
{
i=1,end=p-1;
while(start < end)e= *start, *start++= *end, *end--=e;
}
if(i)start=p+1,i=0;
}while(*p++);
while(src < end)e= *src, *src++= *end, *end--=e;
}

int main()
{
char src[]="thank you,my friend!!!";
printf("%s\n",src);
RevStr(src);
printf("%s\n",src);
return 0;
}
