C++ 字符串

string strMsg="Notify";
 //cout<<strMsg<<endl;//C++不允许直接将类型为string 输出
 strMsg.append("fu");
 char strName[20]="fan";//其余的都赋值为'\0';
 cout<<strName[5]<<endl;

 //int datas[20]={1,2};//整数数组初始化与字符数组初始化不一样，这样会报错
 strcat(strName,"fu");

 cout<<strName<<endl;
 char *pMsg="Notify";
 cout<<pMsg<<endl;
 
 int len=strMsg.length();
 cout<<len<<endl;
 int result;
 cin>>result;
 return 0;
