实现字符串的语序翻转

如输入为“i come from tianjin.”
输出为"tianjin. from come i"

//vs2005#include "stdafx.h"#include <iostream>#include <string>#include <stack>using namespace std;void reverse(char *str){char *p,*q;string s1,s2;s1=str;p=str;q=str;int m=0,n=0;cout<<s1<<endl;stack<string> sstack;while(*q!='\0'){while(*q!=' ')//找到单词结束位置q++,n++;while(*q==' ')//找到单词开始位置q++,n++;s2=s1.substr(m,n-m);sstack.push(s2);p=q;m=n;}while(!sstack.empty()){cout<<sstack.top()<<' ';sstack.pop();}printf("\n");}int _tmain(int argc, _TCHAR* argv[]){char *str="i come from tianjin.";reverse(str);return 0;}
