#include <iostream>
using namespace std;
class string
{
private:
    char *str;
    int len;
public:
    void showstr()
    {cout<<"string:"<<str<<",length:"<<len<<endl;}
    string()
    {len=0;
    str=null;}
    string(char *p)
    {len=strlen(p);
    str=new char[len+1];
    strcpy(str,p);
    }
    ~string()
    {
        if(str!=null)
        {delete [] str;
        str=null;
        cout<<"析构函数被调用"<<endl;
        }
    }
    void main(void)
    {
        char s[]="ABCDE";
        string s1(s);
        string s2("123456");
        s1.showstr();
        s2.showstr();}
运行的时候出现这个错误 fatal error C1004: unexpected end of file found

帮你该了下，错误好多，类都不用括号，还有NULL要大写，不能写string得改个写的方式

#include <iostream>
using namespace std;
class String
{
private:
    char *str;
    int len;
public:
    void showstr()
    {
        cout<<"string:"<<str<<",length:"<<len<<endl;
    }
    String()
    {
        len=0;
    str=NULL;
    }
    String(char *p)
    {len=strlen(p);
    str=new char[len+1];
    strcpy(str,p);
    }
    ~String()
    {
        if(str!=NULL)
        {delete [] str;
        str=NULL;
        cout<<"析构函数被调用"<<endl;
        }
    }
};

    void main(void)
    {
        char s[]="ABCDE";
        String s1(s);
        String s2("123456");
        s1.showstr();
        s2.showstr();
    }

编程的风格不怎么好啊

非常谢谢，我刚学C++，是菜鸟级别的，，，呵呵 能解释下string的用法吗 不胜感激
