c++字符串相连函数

// 介绍两种方法,源程序如下:

//////////////////////////////////////////////////////////////////////
// 方法一:#include <cstring>

#include <iostream>
#include <cstring>
using namespace std;

void main()
{
 string str1 = "abc";
 string str2 = "def";

 cout << "方法一:#include<cstring>" << endl;
 cout << "连接前:" << endl;
 cout << "str1: " << str1.data() << endl;
 cout << "str2: " << str2.data() << endl;

 str1.append(str2);
 
 cout << endl;
 cout << "连接后:" << endl;
 cout << "str1: " << str1.data() << endl;
 cout << "str2: " << str2.data() << endl;
}

/////////////////////////////////////////////////////////////////////
// 方法二:#include <string.h>
/*
#include <iostream.h>
#include <string.h>

void main()
{
 char str1[10] = "abc", str2[] = "def";

 cout << "方法二:#include <string.h>" << endl;
 cout << "连接前:" << endl;
 cout << "str1: " << str1 << endl;
 cout << "str2: " << str2 << endl;

 strcat(str1,str2);

 cout << endl;
 cout << "连接后:" << endl;
 cout << "str1: " << str1 << endl;
 cout << "str2: " << str2 << endl;
}
