C++ string Bug解決方案

#include<iostream>#include<string>#include<fstream>using namespace std;class Test{private:string str;int a;public:Test();Test(string str,int a);void SaveTest();};Test::Test(){str="\0";}Test::Test(string str,int a){this->a=a;this->str=str;}void Test::SaveTest(){fstream outfile,infile;outfile.open("TestFile.txt",ios::out|ios::binary);if(!outfile){                                           cout<<"開啟系統檔案失敗！1\n";    abort();                         }                                    outfile.write((char*)this,sizeof(Test));//<<this->a<<this->str;outfile.close();infile.open("TestFile.txt",ios::in|ios::binary);if(!infile){cout<<"開啟系統檔案失敗！2\n";abort();}Test *t = new Test();infile.read((char*)(t),sizeof(Test)); cout<<t->a<<t->str<<endl;infile.close();outfile.open("TestFile.txt",ios::out|ios::app|ios::binary);if(!outfile){cout<<"開啟系統檔案失敗！3\n";abort();}Test *tes = new Test("hi hi me?", 11);outfile.write((char*)tes,sizeof(Test));outfile.close();infile.open("TestFile.txt",ios::in|ios::binary);if(!infile){cout<<"開啟系統檔案失敗！4\n";abort();}int i;Test* tt[2];for(i=0;i<2;i++){tt[i] = new Test();infile.read((char*)tt[i],sizeof(Test));cout<<tt[i]->a<<tt[i]->str;}infile.close();}           void main(){Test *test = new Test("hello hei!",12);test->SaveTest();}

最好使用建立在棧上的類即new所得，讓程式最後析構。。。
