#include "stdafx.h"
#include<cstring>
#include<string>
#include<iostream>
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
const char *cp1="mary an linda";
const char *cp2="are friends.";
size_t len=strlen(cp1)+strlen(cp2);
char *result_str=new char[len+1];
char *p=*result_str;
while(*p)
cout<<*p++<<endl;
strcpy(result_str,cp1);
strcpy(result_str,cp2);
delete [] result_str;
const string str1("mary an linda");
const string str2("are friends.");
string result_str1;
result_str1=str1;
result_str1+=str2;

return 0;
}

这程序运行不了，那里出错啊？怎么修改？怎么样把result_str1（这个要直接输出，不用循环语句）输出呢？请各位帮帮忙谢谢
